List of top Physics Questions on Alternating current asked in Punjab PMET

An inductor $ L,\,\,a $ capacitor of $ 20\mu F $ and a resistor of $ 10\Omega $ are connected in series with an $AC$ source of frequency $ 50\,Hz $ . If the current is in phase with the voltage, then the inductance of the inductor is

In an $ AC $ circuit the potential difference V and current i are given respectively by $ V=100\sin (100t) $volt and $ i=100\sin \left( 100t+\frac{\pi }{3} \right)mA $ The power dissipated in the circuit will be
