Question

The displacement current was named as current because
(A) It is similar conduction current
(B) It produced a magnetic field
(C) It is a time varying field
(D) It is current due to uniformly moving charge

Answer 1

Hint
A limited shifting of electric components that occurs within a dielectric when a voltage is applied to or removed from it (as in charging or discharging a capacitor) and that corresponds to the current in the circuit supplying the voltage.

Complete step by step answer
The displacement current is not a “real” current, in the sense that it does not describe charges flowing through some region. However, it acts just like a real current. Whenever we have a changing E field, we can treat its effects as due to the displacement current density arising from that field's variations. The displacement current was named as current because it is similar to conduction current. displacement current is the current due to the changing of the electric field inside the plate of the capacitor. so, when the electric field will change, at that tym the displacement current will produce.
Option (A) is correct.

Note
The idea was conceived by James Clerk Maxwell in his 1861 paper On Physical Lines of Force, Part III in connection with the displacement of electric particles in a dielectric medium. Maxwell added displacement current to the electric current term in Ampère's Circuital Law.
