alleryAt the resonant frequency, the two reactances are:
AZero
BAdded
CFixed
DEqual
Answer & Solution
Correct answer: D. Equal
1. Resonance is defined by the cancellation condition.
2. The capacitive reactance matches the inductive reactance.
3. So at resonance the two reactances are equal.
4. The answer is equal.
