An AC voltage source has an RMS voltage of 15 volts and it is connected in series to an inductor, a capacitor, and a resistor. At the resonant frequency the maximum current in the circuit is 9 amps and the inductive reactance is 6 Ohms. What is the maximum current in the circuit, in amps, at a frequency which is a factor of 2.3 more than the resonant frequency?
