Solve the given problem:
Problem: A series RLC circuit contains a 5 microfarad capacitor and a generator whose voltage is 12V. At a resonant frequency of 1.5 kHz the average power delivered to the circuit is 30 W.
Part A: Find the inductance.
Part B: Find the resistance.
Part C: Find the power factor when generator frequency is 2.5 kHz.
