In an rc circuit the power factor
WebSep 17, 2015 · If the resistor and capacitor is connected to a DC source, then it is neither leading nor lagging. If it is connected to an ac source, then the reactive part of the impedance will be capacitive overall (since no inductors are present) and hence the current will lead the voltage. (leading power factor). Answer link WebJun 16, 2024 · Power in Pure Resistor Circuit. The Power in ac circuit of pure resistor is as follows: P o w e r = e i = e o s i n ω t × i o s i n ω t. P = e o i o s i n 2 ω t. The equation of power varies with time. Hence we consider average power. P a v g = work done in one cycle time for one cycle = ∫ 0 T p d t T.
