Problem

A current of

4\ \text{A}

flows in a coil when connected to a

12\ \text{V}

DC source. If the same coil is connected to a

12\ \text{V}

50\ \text{rad s}^{-1}

AC source, a current of

2.4\ \text{A}

flows in the circuit. Determine the inductance of the coil. Also, find the power developed in the circuit if a

2500\ \mu\text{F}

capacitor is connected in series with the coil.
