MCQ
Displacement current is set up between the plates of a capacitor when the potential difference across the plates is ..............
- AMaximum
- BZero
- CMinimum
- ✓Varying
✓
Answer
Correct option: D.
Varying
d
(d)
(d)
Displacement current, $I_d=A \varepsilon_0 \frac{d E}{d t}$
So, the potential difference has to change with time
