MCQ
Current in the circuit is wattless, if
- AInductance in the circuit is zero
- ✓Resistance in the circuit is zero
- CCurrent is alternating
- DResistance and inductance both are zero
✓
Answer
Correct option: B.
Resistance in the circuit is zero
b
(b)Because power $ = {i^2}R,$ if $ R = 0,$ then $ P = 0.$
(b)Because power $ = {i^2}R,$ if $ R = 0,$ then $ P = 0.$
