The opposition offered by a capacitor to alternating current is called:
ACapacitive reluctance
BCapacitive resonance
CCapacitive reactance
DCapacitive resistance
Answer & Solution
Correct answer: C. Capacitive reactance
1. A capacitor also opposes alternating current without dissipating energy.
2. Its opposition falls as the frequency rises.
3. It is called capacitive reactance and is denoted by X sub c.
4. So the answer is capacitive reactance.
