A Series RLC Circuit Is Driven by a 1

Multiple Choice

A series RLC circuit is driven by a 1.0-kHz oscillator. The circuit parameters are L = 5.0 mH, C = 4.0 μF, R = 10 Ω. If you adjust the frequency of the oscillator so that it is at the resonance frequency of the RLC circuit, and if it supplies 3.0 V rms, what is the rms current in the circuit?

A) 0.23 A
B) 0.36 A
C) 0.21 A
D) 0.30 A
E) 0.42 A
