Question

What is the origin of displacement current ?

Answer 1

Displacement current: ... According to Maxwell, a time varying electric field sets up acurrent and hence a magnetic field. Such a current is calleddisplacement current. It follows that a time varying electric field produces a magnetic field and vice -versa.Oct 17, 2018

Answer 2

Variable electromotive force is the cause of displacement current's origin.

• James Clerk Maxwell initially suggested displacement current in his equations describing the behaviour of electric and magnetic fields.
• Displacement current is the term employed in these equations to denote the time-varying electric field that might alter the electric flux across a surface.
• It is connected to the electric displacement field's rate of change, which is a gauge of the electric flux per square metre.
• In order to reconcile the behaviour of electric and magnetic fields as defined by the principles of electrostatics and magnetostatics the notion was developed.
• With the behaviour of these fields, as they travel through space, the notion of displacement current was proposed to explain the behaviour of electromagnetic waves.
