Question

what is displacement current and write its cause

Answer 1

@ranshsangwan

displacement current are the current due to the changing of the electric field inside the plate of capacitor.

so, when the electric field will change , at that tym the displacement current will produce .

HOPE IT HELPS

Answer 2

In electromagnetism, displacement current is a quantity appearing in Maxwell's equations that is defined in terms of the rate of change of electricdisplacement field. Displacement current has the units of electric current density, and it has an associatedmagnetic field just as actual currents do.
