alleryAt resonance the current amplitude in the circuit is:
AHalved
BMaximum
CMinimum
DZero at
Answer & Solution
Correct answer: B. Maximum
1. The impedance drops to R at resonance.
2. Current amplitude is voltage divided by impedance.
3. So the current amplitude is maximum there.
4. The answer is maximum.
