Why is the quantity `in_0(dphi_E)/(dt)` called the displacement curren

1.	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.
Answer» 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.
