CUET and UG exam KEAM Engineering Mock Test Series 2025 Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
An L-C-R series circuit with a resistance of \(100\Omega\) is connected to \(200 V\) (AC source) and angular frequency \(300 \, \text{rad/s}\). When only the capacitor is removed, then the current lags behind the voltage by \(60^\circ\). When only the inductor is removed the current leads the voltage by \(60^\circ\). The average power dissipated in original L-C-R circuit is :
1
\(50 \, W\)
2
\(100 \, W\)
3
\(200 \, W\)
4
\(400 \, W\)
5
\(600 \, W\)
