CUET and UG exam CUET UG 2025 Mock Test Series Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
When 100 V dc is applied across a solenoid, a current of 1A flows in it. When 100 V ac is applied across the same solenoid the current drops to 0.5 A. If the frequency of the ac source is 50 Hz. the impendance and
inductance of the solenoid are:
1
200 Ω and 0.55 H
2
100 Ω and 0.86 H
3
200 Ω and 1.0 H
4
100 Ω and 0.93 H
