Besides an inductor, resonance needs the circuit to contain a:
AVoltmeter
BAmmeter
CCapacitor
DGenerator
Answer & Solution
Correct answer: C. Capacitor
1. Resonance needs the two reactances to cancel each other.
2. One reactance comes from the inductor.
3. The other must come from a capacitor.
4. So the answer is capacitor.
