MCQ
The reactance of a circuit is zero. It is possible that the circuit contains.
- Aan inductor and a capacitor
- Ban inductor but no capacitor
- Ca capacitor but no inductor
- ✓neither an inductor nor a capacitor
✓
Answer
Correct option: D.
neither an inductor nor a capacitor
Answer: $A$ an inductor and a capacitor, $B$ neither an inductor nor a capacitor
Reactance in electrical and electronic systems is the opposition of a circuit element to a change of electric current or voltage.Ideally a resistor has zero reactance.
Therefore in a circuit, reactance can be zero either if there are no inductors and capacitors in the circuit, or the individual reactance of inductors and capacitors cancel each other, making net reactance zero.
