Question: In an AC circuit, if the voltage is 120V and the current is 10A with a power factor of 0.8, what is the real power consumed? (2021)

Options:

Correct Answer: 960W

Exam Year: 2021

Solution:

Real power P = V * I * power factor = 120V * 10A * 0.8 = 960W.

Real Power Calculation – Real power in an AC circuit is calculated using the formula P = V * I * power factor, where V is voltage, I is current, and the power factor accounts for the phase difference between voltage and current.
Power Factor – The power factor is a measure of how effectively the current is being converted into useful work output, with a value between 0 and 1.
