Solution 1

Displacement current is the current that arises in regions where the electric field and electric flux are time-varying.

Solution 2

Maxwell proposed displacement current to explain the continuity of current in circuits with capacitors. It occurs as a result of a time-varying electric field, even in the absence of physical charge flow.

id = `epsilon_0 (d phi_E)/dt`

Where:

ε0 = permittivity of free space

ΦE = electric flux
