Teaching UP PGT Mock Test Series 2024 Physics Electromagnetic Oscillations and Alternating Current Power in Alternating-Current Circuits
An LCR circuit contains resistance of 110 Ω and a supply of 220 V at 300 rad/s angular frequency. If only capacitance is removed from the circuit, the current lags behind the voltage by 45°. If on the other hand, only the inductor is removed the current leads by 45°. If on the other hand, only the inductor is removed the current leads by 45° with the applied voltage. The ms current flowing in the current circuit will be:
1
1 A
2
1.5 A
3
2 A
4
2.5 A
