# Impedance and Resonance Frequency of a Circuit

Consider a series RLC circuit with R=15 ohm, L=200mH,C=75uf, and a maximum voltage of 150V.

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 percent below the resonant frequency, or at 10 percent above the resonant frequency?

d) What is the rms current in the circuit at a frequency of 60 Hz?
