railway DFCCIL Junior Executive 2023 (CBT 1 & CBT 2) Mock Test Network Theory Sinusoidal Steady State Analysis
If the voltage and current in an AC circuit are represented as \(v = 240\sin \left( {314t - \frac{\pi }{6}} \right)\) and \(i = 40\sin \left( {314t + \frac{\pi }{3}} \right)\), then the power factor of the circuit is:
1
30° leading
2
Unity
3
Zero lagging
4
Zero leading
