(a) At what frequency must the circuit in Problem 24 be operated for the current to lead the voltage by 25.0°? In problem 24 A 50.0-Hz generator with an rms voltage of 115 V is connected in series to a 3.12-kΩ resistor and a 1.65-μF capacitor. Find (a) The rms current in the circuit (b) The phase angle, f, between the current and the voltage. (b) Using the frequency found in part (a), find the average power consumed by this circuit.
