Why is the quantity in0(dphiE)/(dt) call...

Why is the quantity `in_0(dphi_E)/(dt)` called the displacement current? Where `dphi_E//dt` is the rate of change of electric flux linked with a region or space.

Text Solution

Verified by Experts

The quntitity `in_0 (dphi_E)/(dt)` has the dimension of
current and this currents exists in a region
between the two plates of capacitor when
displacement of charges occurs there. i.e., during
charging or discharging of capacitor.
