Question

what is unit of Displacement current

Answer 1

In electromagnetism, displacement current is a quantity appearing in Maxwell's equations that is defined in terms of the rate of change of electric displacement field. Displacement current has the same units as electric current, and it is a source of the magnetic  field just as actual current is.

Answer 2

Heya friend!!
Rajdeep here....

SI unit of current is Ampere.
Displacement current has its unit same as that of current. Displacement current is actually the source of the magnetic field, like an actual current. So you can say that its unit, too, is Ampere (A).

Thanks!
