Teaching HTET PGT Level 3 - 2024 Mock Test Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
A series LCR circuit containing 5.0 H inductor, 80 µF capacitor and 40 Ω resistor is connected to 230 V variable frequency ac source. The angular frequencies of the source at which power transferred to the circuit is half the power at the resonant angular frequency are likely to be :
1
42 rad/s and 58 rad/s
2
25 rad/s and 75 rad/s
3
50 rad/s and 25 rad/s
4
46 rad/s and 54 rad/s
