Single Phase Power

July 25, 2021 / Electrical / 4 minutes of reading

Single phase power refers to the distribution system in which; all the voltages vary in unison. It can be generated simply by rotating a moving coil in a magnetic field or by moving field around a stationary coil. The alternating voltage and alternating current so produced, thus referred to as single phase voltage and current. …

Let us consider a single phase power circuit in which current lags behind the voltage by an angle φ.Let the instantaneous electric potential difference v = Vm.sinωtThen the instantaneous current can be expressed as i = Im. sin(ωt – φ).Where, Vm and Im are the maximum values of sinusoidally varying electric potential difference and current …
