Equation for ac power
WebJan 24, 2024 · Power in AC Circuit In the case of a steady current, the rate of doing work is given by \ (P=V i\) In an alternating circuit, both current and voltage vary with time, and … WebMay 22, 2024 · The power in the load can be determined by using I2R where I = E / (Ri + R), yielding. P = ( E Ri + R)2R. Using our normalized values of 1 volt and 1 Ω, P = ( 1 1 + R)2R. After expanding we arrive at: P = R R2 + 2R + 1. We now have an equation that describes the load power in terms of the load resistance.
