Problem

An L-C-R series circuit with

100 \Omega

resistance is connected to an AC source of

200 \text{ V}

and angular frequency

300 \text{ rad/s}

. When only the capacitance is removed, the current lags behind the voltage by

60^\circ

. When only the inductance is removed, the current leads the voltage by

60^\circ

. Calculate the current and the power dissipated in the L-C-R circuit
