A circuit is operated at its resonant frequency, which is designed to be 240 Hz. The circuit contains a toroid that provides an inductance of 370 mH, and has a total resistive load of 1250 Ohms. Due to the passage of time, eventually the frequency decreases to 220 Hz. If when operating under design conditions it used an average power of 440 W, find: a) The capacitance of the circuit. b) The peak and rms current and voltage at which it operates under design conditions. c) The peak and rms current and voltage at which it operates under conditions after heavy use. d) The power factor in the condition after much use.
