Question
Choose the correct answer from the alternatives given.
Displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor.
✓

Answer

  1. increases or decreases
Explanation:
Displacement current inside a capacitor is given by:-
$\text{i}_\text{d}=\epsilon_0\frac{\phi\text{E}}{\text{dt}}$
where $\phi_\text{E}$​ is the electric flux inside the capacitor
The displacement current is developed inside a capacitor when there is a change in the electric flux linked with the capacitor.
The change in electric flux can occur in both the cases either the charge increases or decreases on the capacitor. This will lead to a change in flux linked with the coil.
