Maximum power is dissipated in a series LCR circuit at:
ALow current
BResonance
CZero volts
DHigh phase
Answer & Solution
Correct answer: B. Resonance
1. Power dissipation follows the current through R.
2. The current peaks when impedance is least.
3. That happens at resonance.
4. So the answer is resonance.
