Consider a series RLC circuit with R = 15 , L = 200 mH, C = 75 µ F, and a maximum voltage of 150 V. (a) What is the impedance of the circuit at resonance (b) What is the resonance frequency of the circuit (c) When will the current be greatest: at resonance, at 10% below the resonant frequency, or at 10% above the resonant frequency (d) What is the rms current in the circuit at a frequency of 60 Hz
