JEE Main 2021 — Alternating Current Question with Solution
From: JEE Main 2021 (Online) 25th February Evening Shift
Question
An LCR circuit contains resistance of 110 and a supply of 220 V at 300 rad/s angular frequency. If only capacitance is removed from the circuit, current lags behind the voltage by 45. If on the other hand, only inductor is removed the current leads by 45 with the applied voltage. The rms current flowing in the circuit will be :
