Problem: The inductor has a reactance of 50 ohms and an inductance of 240 mH. A 50-ohm resistor and a capacitor whose reactance is 140 ohms are also in the circuit. The RMS current in the circuit is 1.2 A. The capacitor is changed so that the circuit is in resonance. The voltage of the source is adjusted so that the RMS current of 1.2 A is maintained.

A- What is the new voltage amplitude of the source?

Please explain the equations and steps are used to get the answer. Thanks!
