QNEET-2021-Ph-609: NEET 2021 Physics - Class 12 NEET-2021-Ph-609 Solution: A series LCR circuit containing 5.0 H inductor 80 \( F\)…
A series LCR circuit containing 5.0 H inductor 80 capacitor and 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: 42 rad/s and 58 rad/s 25 rad/s and 75 rad/s 50 rad/s and 25 rad/s 46 rad/s and 54 rad/s
Multiple Choice Options
- A 42 rad/s and 58 rad/s
- B 25 rad/s and 75 rad/s
- C 50 rad/s and 25 rad/s
- D 46 rad/s and 54 rad/s
