A MOSFET operates as a linear resistance when the voltage applied between its source and drain terminals is small.

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a three-terminal device commonly used in electronic circuits as a voltage-controlled switch or amplifier. It consists of a gate terminal, a source terminal, and a drain terminal.

In its normal operation, the MOSFET can be categorized into two regions: the cutoff region and the saturation region. In the cutoff region, the MOSFET is effectively turned off, and no current flows between the source and drain terminals. In the saturation region, the MOSFET is turned on, and a significant current can flow between the source and drain terminals.

However, there is also a region known as the linear or triode region, where the MOSFET operates as a linear resistance. In this region, the MOSFET is partially turned on, and the current flowing between the source and drain terminals is proportional to the voltage applied across them.

When the voltage applied between the source and drain terminals is small, the MOSFET operates in the linear region. In this region, the MOSFET can be used as a variable resistor, and its resistance can be controlled by adjusting the gate voltage. The MOSFET behaves linearly, similar to a conventional resistor, and can be utilized in applications such as voltage amplifiers or signal processing circuits.

However, it's important to note that the linear resistance operation of a MOSFET is limited to small voltage ranges. Beyond a certain threshold voltage, the MOSFET will enter the saturation region, where it behaves as a current source rather than a linear resistor.

The designed unity feedback system has the transfer function G(s) = 0.1(s+√10)/(s+10)², with K = 0.1, a = √10, and B = 10.

To design the unity feedback system with the given specifications, we start by determining the desired characteristics of the system.

Since the steady-state error for a unit step input is specified as 0.1, we know that the system needs to have zero steady-state error. This means that we need to add an integrator to the system.

Next, we determine the desired damping ratio and natural frequency. The damping ratio is given as 0.5, and the natural frequency is given as √10. From these values, we can find the values of a and B in the transfer function.

Using the damping ratio and natural frequency, we can calculate the values of a and B as follows:

a = 2ζωn = 2(0.5)(√10) = √10

B = ωn² = (√10)² = 10

Now, we have the transfer function G(s) = K(s+√10)/(s+10)².

To determine the value of K, we use the steady-state error requirement. Since the steady-state error for a unit step input is specified as 0.1, we can use the final value theorem to find the value of K:

K = lim(s→0) sG(s) = lim(s→0) sK(s+√10)/(s+10)² = 0.1

Solving this equation, we find that K = 0.1.

Therefore, the designed unity feedback system has the transfer function G(s) = 0.1(s+√10)/(s+10)², with K = 0.1, a = √10, and B = 10.

An envelope detector is an electronic circuit that helps in removing or extracting the envelope of a modulated signal. It rectifies an AC signal and filters it to obtain the envelope. The input to an envelope detector is

s(t)=10cos(20πt)cos(8000πt)+10sin(8000πt)The signal s(t) can be written as:s(t)=10cos(20πt)cos(8000πt)+10sin(8000πt)=5[cos(2π(4000)t + cos(2π(12000)t)]

Applying the envelope detector: The rectified signal can be written asy(t) = |s(t)| = |5[cos(2π(4000)t + cos(2π(12000)t)]|= 5[|cos(2π(4000)t)| + |cos(2π(12000)t)|]

The envelope of the rectified signal can be obtained by passing the rectified signal through a low-pass filter, which removes the high-frequency components.

Here, we assume that the low-pass filter has a time constant much larger than the period of the modulating frequency.

The output of the envelope detector can be written as: Vout = y(t) * h(t)where h(t) is the impulse response of the low-pass filter.

The impulse response of a low-pass filter can be written as

h(t) = (1/τ) * exp(-t/τ)

where τ is the time constant of the filter. Substituting the value of y(t) and h(t), we get

Vout = y(t) * h(t) = 5[|cos(2π(4000)t)| + |cos(2π(12000)t)|] * (1/τ) * exp(-t/τ)Thus, the output of the envelope detector is 5[|cos(2π(4000)t)| + |cos(2π(12000)t)|] * (1/τ) * exp(-t/τ).

Step 1: Applying the constraint p(0) = a
Substituting u = 0 into the polynomial equation, we have:
p(0) = C₁ + C₁(0) + C₂(0)² = C₁ = a

Step 2: Applying the constraint p(1) = b
Substituting u = 1 into the polynomial equation, we have:
p(1) = C₁ + C₁(1) + C₂(1)² = C₁ + C₁ + C₂ = 2C₁ + C₂ = b

Step 3: Applying the constraint p'(0) = c
Differentiating the polynomial equation with respect to u, we get:
p'(u) = C₁ + 2C₂u
Substituting u = 0 into the derivative equation, we have:
p'(0) = C₁ + 2C₂(0) = C₁ = c

From Step 1 and Step 3, we have determined that C₁ = a and C₁ = c, which means a = c.

Step 4: Substituting C₁ = a into the equation from Step 2
Using the fact that a = c, we have:

The given value of D is:D= 5x2ax+10zm(C/m2)To find the net outward flux crossing the surface of a cube 2 m on an edge centered at the origin, we need to use Gauss's Law, which states that:The flux of a vector field through a closed surface is proportional to the enclosed charge by the surface.Φ = QEwhere:Φ = FluxQ = Enclosed chargeE = Electrical permittivity of free spaceThe enclosed charge (Q) is the volume integral of the charge density ρ over the volume V enclosed by the surface S. So, Q = ∫∫∫V ρdV = ρVWhere:ρ = charge densityV = VolumeTherefore, Φ = (1/ε)ρV.Here,ε = Electrical permittivity of free space = 8.85 × 10^−12 C²/(N.m²) andρ = 5x²a + 10zm.So, Q = ρV = 5x²a + 10zm × volume of cube = 5x²a + 10zm × (2 m)³ = 5x²a + 80zm m³.

Now, the total charge enclosed by the cube is the summation of all the charges enclosed by each face.Each face of the cube has an area of 2 m × 2 m = 4 m², and since the edges of the cube are parallel to the axes, each face is perpendicular to one of the axes.So, by symmetry, the flux through each face is equal, and the net flux through the cube is 6 times the flux through one of the faces.So, Φ = 6 × Flux through one faceΦ = 6 × (Φ/6) = Φ/εNow, the area of one face of the cube is A = 4 m², and the electric field E is perpendicular to the face of the cube, so the flux through one face is given by:Φ = E × A = E × 4m².Using Gauss's Law,Φ = Q/ε = (5x²a + 80zm m³)/ε.Substituting this into the expression for the flux through one face, we get:E × 4m² = (5x²a + 80zm m³)/ε. Solving for E, we get:E = (5x²a + 80zm m³)/(ε × 4m²)E = (5x²a + 80zm)/35 C/m².The total flux through the cube is:Φ = 6 × Flux through one face = 6 × E × A = 6 × (5x²a + 80zm)/35 C/m² × 4 m² = (8/35) × (5x²a + 80zm) C.The net outward flux is the flux through one face since each face has the same outward flux crossing. Thus,Net outward flux = E × A = (5x²a + 80zm)/35 C/m² × 4 m² = (8/35) × (5x²a + 80zm) C = (8/35) × (5(0)²a + 80(0)m) C = 0 + 0 C = 0 C.Hence, the net outward flux crossing the surface of a cube 2 m on an edge centered at the origin is 0 C.

The given problem involves finding the electric field and electric potential due to a spherically symmetric charge density. To find the electric field and potential, two methods are used: Gauss's law and Poisson-Laplace equations.

(a) Gauss's law: According to Gauss's law, the electric field due to a spherically symmetric charge distribution can be obtained using the formula, φ = ∫ E · dA = Q/ε, where Q is the total charge enclosed by the Gaussian surface and ε is the permittivity of free space. The Gaussian surface in this case is a sphere of radius r and the enclosed charge is given by ∫ p(r) dV = Po∫ er^2 dr= Po[e^(r^2) / 2] between r = 0 to r = r. Thus, the total charge enclosed is Q = Po[e^(r^2) / 2] * 4πr^2. The electric field at any point inside the sphere is radially outward and has a magnitude E = Q/(4πεr^2). Therefore, the electric potential at any point inside the sphere is given by the formula, φ = - ∫ E · dr = - ∫ Q/(4πεr^2) dr = Po[e^(r^2) / 2πεr] + C.

(b) Poisson-Laplace equations: The Poisson-Laplace equations relate the charge density to the electric potential. The Laplacian operator is denoted by ∇^2 and the charge density is given by p(r) = Po[e^(r^2) / 2]. Therefore, we have ∇^2 φ = - p/ε. Substituting the given values, we get ∇^2 φ = - Po[e^(r^2) / 2ε].

The given differential equation is solved as follows: φ(r) = Ar * erf(r/(2√(ε))) + Br * erfc(r/(2√(ε))), where A and B are constants and erf and erfc are the error functions. The boundary conditions provided are φ(0) = 0 and φ(r → ∞) = 0. Applying these boundary conditions, we get the expression: φ(r) = Po * (erfc(r/(2√(ε))) - 1). Therefore, the electric potential created by a spherically symmetric volume charge density can be represented as φ(r) = Po[e^(r^2) / 2πεr] + C or φ(r) = Po * (erfc(r/(2√(ε))) - 1).

The total energy of the system is calculated by integrating the energy density over the sphere's volume. The energy density is represented by u = (1/2)εE^2 = (1/2)ε(Q/(4πεr^2))^2 = Q^2/(32π^2εr^4). The total energy U can be computed as U = ∫ u dV = ∫ (Q^2/(32π^2εr^4)) * 4πr^2 dr = Q^2/(8πεr) = Po^2[e^(r^2)]/(8πεr).

The resistance (R) of the circuit is 25 Ω, the capacitance (C) is approximately 1.96 μF, and the inductance (L) is approximately 5.92 mH.

Resistance (R): 25 Ω

Capacitance (C): 1.96 μF

Inductance (L): 5.92 mH

In a series RLC resonant circuit, the quality factor (Q) is defined as the ratio of the reactance to the resistance. Calculation for the same is:

Q = X / R

where X is the reactance, R is the resistance, and Q is the quality factor.

At resonance, the reactance of the inductor (XL) is equal to the reactance of the capacitor (XC). Reactance of the inductor:

XL = 2πfL

XC = 1 / (2πfC)

where C is the capacitance.

Since the reactances are equal at resonance, we can equate the two expressions:

2πfL = 1 / (2πfC)

Simplifying the equation:

L = 1 / (4π²f²C)

Given that the frequency f is 455 kHz and the quality factor Q is 80, we can substitute these values into the equation:

L = 1 / (4π²(455,000 Hz)²C)

To find the capacitance C, we can rearrange the equation:

C = 1 / (4π²(455,000 Hz)²L)

Substituting the values, we can find the capacitance C.

To find the resistance R, we can use the formula for the quality factor:

Q = X / R

Since the reactance X is equal to the resistance R at resonance, we can substitute the maximum current and the supply voltage into the formula:

Q = (2πfL) / R

Solving for R, we get:

R = (2πfL) / Q

Substituting the given values, we can find the resistance R.

The power required for dielectric heating of a slab of resin 150 cm² in area and 2 cm thick is 200 W. The frequency required to obtain the same heating at a voltage of 700 V is 51.6 MHz.

Given: Area of slab of resin = 150 cm²

Thickness of slab of resin = 2 cm

Power required for dielectric heating = 200 W

Frequency = 30 MHz

Relative permittivity = 5

Power factor = 0.05

To find:

Voltage necessary and the current flowing through the material.

If the voltage is limited to 700 V, what will be the frequency to obtain the same heating?

Formula used: The formula used for power required for dielectric heating is given as:

P = 2πfε0εrE0^2tanδ

Where, P = Power

f = Frequency

ε0 = Permittivity of free spaceεr = Relative permittivity

E0 = Electric field strength

tanδ = Power factor

E0 = Electric field strength = V/d

Where, V = Voltage

d = distance between the plates.

Calculation:

Area of slab of resin = 150 cm²

Thickness of slab of resin = 2 cm

So, volume of slab of resin = 150 cm² × 2 cm= 300 cm³

As we know, V = Q/C

Where,Q = Charge

C = Capacitance

C = εrε0A/d

Where, A = Area of the slab of resin = 150 cm²

εr = Relative permittivity = 5

ε0 = Permittivity of free space = 8.85 × 10^−12F/m2d = Thickness of the slab of resin = 2 cm = 0.02 m

Putting all the values, we get:

Capacitance C = εrε0A/d= 5 × 8.85 × 10^-12 × 150 × 10^-4/0.02= 5.288 × 10^-11F

Now, to calculate the electric field strength E0, we can use the power formula,

P = 2πfε0εrE0^2tanδ

Where, P = Power = 200 W

f = Frequency = 30 MHz = 30 × 10^6Hz

ε0 = Permittivity of free space = 8.85 × 10^−12F/m2

εr = Relative permittivity = 5

tanδ = Power factor = 0.05

On putting all the values in the formula, we get:

200 = 2π × 30 × 10^6 × 8.85 × 10^-12 × 5 × E0^2 × 0.05

On solving, we getE0 = 2.087 × 10^4Vm^-1Now, as we know that:

Electric field strength E0 = V/d

So, on substituting the values we get

2.087 × 10^4 = V/0.02V = 417.4 V

Current flowing through the material is given:

asI = P/V= 200/417.4= 0.48 A

Frequency when voltage is limited to 700 V, we have to calculate the frequency.

f = 2π√(f/μεr) × V/d

On putting all the values, we get:

f = 2π√(700 × 2 × 10^-2 × 0.05)/(8.85 × 10^-12 × 5)= 51.6 MHz.

Hence, the frequency required to obtain the same heating at a voltage of 700 V is 51.6 MHz.

The given expression for the electric field of a traveling electromagnetic wave is E = -20 cos(7x10t), where E is in volts per meter (V/m), t is time in seconds (s), and x is the spatial coordinate.

Direction of wave propagation:

The direction of wave propagation is not explicitly provided in the given expression. To determine the direction, we would need information such as the sign of the coefficient of 'x' in the argument of the cosine function. However, it is not mentioned in the expression, so the direction cannot be determined.

Wave frequency (f):

From the given expression, we can see that the coefficient of 't' is 7x10, which represents the angular frequency (ω) of the wave. The angular frequency is related to the frequency (f) by the equation ω = 2πf. Therefore, we can calculate the frequency as follows:

ω = 7x10

2πf = 7x10

f = (7x10) / (2π)

f ≈ 3.53 Hz

So, the wave frequency is approximately 3.53 Hz.

Wavelength (λ):

The wavelength (λ) of a wave is related to its frequency (f) and the speed of light (c) by the equation λ = c / f. However, the speed of light (c) is not provided in the given expression, so we cannot calculate the wavelength.

A DC motor's direction of rotation can be changed by reversing the direction of the electric current flowing through it. DC motors can be easily reversed by reversing the polarity of their power supply, which switches the direction of the current flowing through the motor's coils.

To make a DC motor reversible, you will need to attach a reversible switch to it, which will enable you to switch the direction of the current flowing through it, thus reversing the motor's direction of rotation. To reverse the polarity of a DC motor's power supply, one common method is to use a double-pole, double-throw (DPDT) switch, which can switch the direction of the current flowing through the motor's coils by reversing the polarity of the power supply.

A DPDT switch can be wired to a DC motor in the following way: the motor's positive (+) power lead is connected to one of the switch's center terminals, while the negative (-) power lead is connected to the other center terminal. The two outer terminals are then connected to the power supply, with one being connected to the positive (+) side and the other to the negative (-) side of the power supply.

To reverse the direction of the motor's rotation, the switch is flipped to the other position, which reverses the polarity of the power supply and switches the direction of the current flowing through the motor's coils, thus reversing its direction of rotation.
