In a series LCR circuit C=20 μF and angular frequency of supply voltage is ω = 100 rad/s. What is the value of L in henry if current in the circuit is maximum?

Since the current is maximum means the circuit is in resonance.The resonating frequency is ω=1LC                                  ⇒L=1ω2C=1104x20x10-6                                  ⇒L=10020=5 H
