The average power dissipated in an RLC series circuit at resonance is dependent upon
A) the frequency.
B) the capacitive reactance.
C) the inductive reactance.
D) the resistance.

Question

Quizplus · Accepted Answer

The average power dissipated in an RLC series circuit at resonance is dependent upon the resistance. At resonance, the capacitive and inductive reactances cancel each other out, resulting in a purely resistive circuit. Therefore, the power dissipated is determined only by the resistance in the circuit.
