MCQ
The reactance of a circuit is zero. It is possible that the circuit contains:
- ✓An inductor and a capacitor.
- BAn inductor but no capacitor.
- CA capacitor but no inductor.
- DNeither an inductor nor a capacitor.
✓
Answer
Correct option: A.
An inductor and a capacitor.
$\text{X}=0$ (Given)
$\text{X}=\text{X}_\text{L}+\text{X}_\text{C}$
$=\omega\text{L}-\frac{1}{\omega\text{C}}=0$
It is possible that the circuit contains an inductor and a capacitor.
$\text{X}=\text{X}_\text{L}+\text{X}_\text{C}$
$=\omega\text{L}-\frac{1}{\omega\text{C}}=0$
It is possible that the circuit contains an inductor and a capacitor.
