Alternating Current: NEET 2020

Medium· Power in AC Circuits: the Power Factor· +4 / −1

A series LCR circuit is connected to an ac voltage source. When L is removed from the circuit, the phase difference between current and voltage is

\frac{\pi}{3}

. If instead C is removed from the circuit, the phase difference is again

\frac{\pi}{3}

between current and voltage. The power factor of the circuit is :
