An LRC circuit consists of a 15.0 μF capacitor, a resistor, and an inductor connected in series across an AC power source of variable frequency having a voltage amplitude of 20.0 V. You observe that when the power source frequency is adjusted to 44.5 Hz, the rms current through the circuit has its maximum value of 65.0 mA. What will be the rms current if you change the frequency of the power source to 60.0 Hz? {? A}
