Physics · Alternating Current
L1-C1-R1 is a series AC circuit with an RMS voltage source E1 and variable frequency ν. L2-C2-R2 is a second series AC circuit with an RMS voltage source E2 (where E2 > E1) and variable frequency. Resonance curves plotting the current amplitude (I0) versus frequency (ν) show that both circuits achieve peak current at the exact same resonant frequency, with the peak current of the second circuit being higher. Which of the following relations is correct?
