Tanmay Joshu 8 years, 1 month ago

Displacement current is the current due to change in magnetic flux. No electronic moment is involved in this.

Kritika Trehan 8 years, 1 month ago

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.
