The reactance of a circuit is zero. It is possible that the circuit contains:
A. an inductor and a capacitor
B. an inductor but no capacitor
C. a capacitor but no inductor
D. Neither inductor nor capacitor
Choose the correct answer from the options given below:
- A A & B Only
- B A, B and C Only
- C D and C Only
- D A & D Only
Answer & Solution
Correct Answer
(D) A & D Only
Step-by-step Solution
Detailed explanation
For zero reactance \( X = X_L - X_C = 0 \). A. An inductor and a capacitor: Possible if \( X_L = X_C \) (resonance). B. An inductor but no capacitor: Not possible for \( \omega \ne 0, L \ne 0 \). C. A capacitor but no inductor: Not possible for \( \omega \ne 0, C \ne 0 \). D.…
