WebNov 27, 2024 · In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance. The average power delivered to an RLC circuit is affected by the phase angle. The power factor ranges from –1 to 1. 15.6 Resonance in an AC Circuit WebNov 25, 2024 · Power Factor. In an AC circuit, the power factor plays a vital role. It is the factor that decides the amount of real power flowing in the circuit. The power factor is the cosine of the angle between the voltage and the current waveforms. It is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit.
