explain the sphere gap method of measuring dc ac and impulse voltages

Answers

Answer 1

Answer:

The voltage to be measured is applied between the two spheres and the distance or spacing S between them gives a measure of the sparkover voltage. ... In the case of a.c. peak value and d.c. voltage measurements, the applied voltage is uniformly increased until sparkover occurs in the gap.

Answers

Answer:

B the EOQ after setup reduction.

Through a program of setup reduction, thesetup cost is reduced to $20. Run costs are $2 per unit. CalculateThe EOQ after setup reduction. Hence, option B is correct.

What is meant by EOQ?

The amount of an order known as a "economic order quantity" (EOQ) is one that lowers the overall cost of acquiring and maintaining inventories of goods or raw materials.

The supplier should be contacted to ascertain the optimal inventory size in order to lower the company's overall annual inventory cost. Economic order quantity, or EOQ, is the phrase. Supply, logistics, and operations management all use this measurement.

In its most basic form, EOQ is a technique for determining the quantity and frequency of orders required to satisfy a particular level of demand while reducing the cost per order.

Thus, option B is correct.

The heated water can then be sent to hot water faucets in a building. Assume that a water heater design requires the hottest water possible to be sent to hot water faucets in a building. Where would be the best place for the hot water outlet pipe to be attached to the tank: the top, the middle, or the bottom of the tank? Explain your answer.

Explanation:

I think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top.

What is Heater?

The process of transforming electrical current into heat energy is known as electric heating. An electrical resistor serves as the heating element in an electric heater, and heat is generated there when an electric current flows through it.

This procedure is frequently utilized in a wide range of domestic applications. from using an electric burner to prepare food, a kettle to boil water, and of course, house heating.

With one significant exception—they don't rely on a boiler and a system of pipes to produce the heat—electric heaters and radiators function exactly like your central heating radiators that are plumbed in.

Answer:

C

Explanation:

As horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

What is horsepower?

Horsepower is defined as a unit used to describe the pace at which labor is done or to quantify power, frequently in relation to the output of engines or motors. Standardization and types of horsepower vary widely. A car's engine power is measured in horsepower (hp); the greater the number, the more power is transferred to the wheels and, in theory, the faster it will travel.

To put it simply, horsepower is your overall speed and power, whereas torque allows you to feel the sensation of acceleration when you put your foot down. When you realize that horsepower is derived from torque, this makes sense. Torque is a unit of rotational or twisting force. The power an engine produces is referred to as horsepower.

Thus, as horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

State Conditions necessary for static equilibrium of a particle of a rigid body​

Answers

Answer:

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.

Hi there!

For a particle to be in static equilibrium:

[tex]\huge\boxed{\Sigma \tau = 0}}[/tex]

The sum of torques acting on the particle must equal 0 Nm.

Which of the following is a Dashboard Scoreboard for alignment of the business where information is constantly flowing through the Tiers so immediate actions can be taken?

Answers

Answer:

What is a dashboard?

A dashboard is an information management tool used to track KPIs, metrics, and key data points that are relevant to your business, department, or a specific process. Dashboards aggregate and visualize data from multiple sources, such as databases, locally hosted files, and web services. Dashboards allow you to monitor your business performance by displaying historical trends, actionable data, and real-time information.

Dashboards actually take their name from automobile dashboards and they are used in much the same way. For the sake of an analogy, let’s look at a car. There may be hundreds of processes that impact the performance of your vehicle if you look under the hood. Your car’s dashboard summarizes this using visualizations so you can focus on what matters most: safely driving your vehicle.

For businesses, there are hundreds of processes that impact your performance if you look ‘under the hood’, so to speak. And with a wealth of data made available these days, managing and extracting value from it can be difficult. Simplifying data analysis and distribution through tools like dashboards is a way to help businesses rev their engines and make smarter, better, faster data-driven decisions.

And a well designed dashboard levels up your approach to information management. Everyone in the business, regardless of role, has questions about your company performance, whether it be campaign performance, new wins, or churn rate. Dashboards bring everyone (and your metrics) together in one place to answer these questions.

Explanation:

A positively charged electric has a charge of 2 Coulombs. If 12.5x10^18 free electrons are added to it, what will be the net charge on the said dielectric?

Answers

The net charge on the said dielectric is 0

1C = 6.25 * 10¹⁸ electrons; hence:

-12.5x10¹⁸ free electrons = (-12.5x10¹⁸ free electrons * (1C/ 6.25 * 10¹⁸ electrons))

-12.5x10¹⁸ free electrons = -2 C

A positively charged electric has a charge of 2 Coulombs, hence:

Q₁ = 2C

12.5x10¹⁸ free electrons are added to it, hence:

Q₂ = -2C

[tex]Net\ charge(Q_{net})=Q_1+Q_2=2C+(-2C)=0[/tex]
