It should be noted that the resistor is NOT within its tolerance rating since the value of R = 1,300Ω.
What is a Tolerance Rating?The tolerance of a resistor is its variation from its nominal value. It is presented as a percentage and was tested at 25°C with no load applied. Tolerances on certain resistor designs are exceedingly tight. Precision wire-wound resistors, for example, are manufactured with tolerances as fine as 0.005%.
The resistor value may be estimated using the resistor color coding table. The value of resistance may be calculated using Ohm's law.
Ohm's law asserts that if all physical conditions and temperatures are constant, the voltage across a conductor is precisely proportional to the current flowing through it. The proportionality constant, R, is denoted by the symbol Ω and has units of ohms in the equation.
With regard to the above problem, we know that:
The markings of the resistor (bands) are:
Brown = 1
Black = 0
Red = 10²
Gold ± 5%
Hence, the value of the resistor is:
Rt (Resistance True Value) = 10 x 10² ± 5%
Where ±5 is the tolerance level
Rt = 1000 ± 5% ⇒ 950Ω to 1050Ω
Referencing Ohms Law,
R = V/I
Where
R = Resistance
V = Voltage
I = Current
R = 6.5/5mA
R = (6.5/5) x 10³
R = 1.3 x 10³
R = 1, 300Ω
Since Measure Resistance 1, 300Ω is greater than the Resistance True value, we can conclude that the resistor is NOT within its tolerance rating.

Which two energy sources together provided more than 50 per cent of the energy needs of the USA in the year 1980
Hydropower 5%
Nuclear 4%
Other (wind, solar, geothermal) 1%
Coal 23%
Natural Gas 25%
Oil 42%
Options:
a) Nuclear and natural gas
b) Oil and coal
c) Hydropower and oil
d) Natural gas and coal
The two energy sources that combined together to provide more than 50 percent of the energy needs of the USA in the year 1980 is: b) Oil and coal.
What is energy?In Science, energy can be defined as a measure of the ability of a physical body to do work. This ultimately implies that, energy must be possessed or transferred to a physical object or physical body before it can be used in doing a work or heating a system.
The forms of energy.In Science, there are different forms of energy and these include the following;
Wind energyKinetic energy.Gravitational energy.Potential energy.Elastic energyChemical energy.Solar energy.Nuclear energy.Based on the information provided, the two energy sources that would provide more than 50 percent of the energy needs of the USA in the year 1980 when added together should be calculated as follows:
Nuclear and natural gas = 4% + 25% = 29% (less than 50 percent).
Oil and coal = 42% + 23% = 75% (more than 50 percent).
Hydropower and oil = 5% + 42% = 49% (less than 50 percent).
Natural gas and coal = 25% + 23% = 48% (less than 50 percent).
