Consider a series RLC circuit with R = 15 , L = 196 mH, C = 75 µF, and a maximum voltage of 148 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 ten percent below the resonant frequency, or at ten percent above the resonant frequency?
The current is a maximum at ten percent above the resonant frequency.The current is a maximum at ten percent below the resonant frequency. The current is a maximum at resonance.
(d) What is the rms current in the circuit at a frequency of 60 Hz?
