# Displacement Current Goes Through the Gap Between the Plates of a Capacitor When the Charge of the Capacitor - Physics

Short Note

Displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor

(a) increases
(b) decreases
(c) does not change
(d) is zero

#### Solution

(a) increases
(b) decreases

Displacement current inside a capacitor,

i_d = ∈_0 (dΦ_E)/dt ,  Where

Φ_E is the electric flux inside the capacitor.
Up to the time the electric flux changes, there will be a displacement current. This is possible when the charge on a capacitor changes. Therefore, the displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor or electric field increases or decreases inside the capacitor.

Is there an error in this question or solution?
