Question

what is displacement current? why did maxwell introduces the concept of displacement currrent?​

Answer 1

We know that an electric current produces a

magnetic field around it. J.C. Maxwell showed that

for logical consistency, a changing electric field

must also produce a magnetic field. Further, since

magnetic fields have always been associated with

currents, Maxwell postulated that this current was

proportional to the rate of change of the electric

field and called it displacement current. In this

article, we will look at displacement current in

detail.
