Explanation: As the load is RL, the load current will be maximum when the output voltage waveform falls to zero i.e. at π. At π the inductor is charged to its maximum value and starts delivering power to the source. 7. For a single phase, full bridge, diode rectifier excited from a 230 V, 50 Hz source. With R = 10 Ω & the inductance(large enough to maintain continuous conduction, the value of the supply power factor will be
A. 0.707 lag
B. 0.9 lag
C. 0.86 lag
D. Unity
