MCQ
Displacement current is continuous:
- ✓when electric field is changing in the circuit
- Bwhen magnetic field is changing in the circuit
- Cin both types of fields
- Dthrough wires and resistance only
✓
Answer
Correct option: A.
when electric field is changing in the circuit
Displacement current is a quantity appearing in Maxwell's equations that is defined in terms of the rate of change of electric displacement field.
When electric field is changing with time continuously, the displacement current is constant.
