Displacement current is a type of current that is associated with the propagation of electromagnetic waves in a conductor. It is a special form of current that is caused by the acceleration of charges in the conductor. These charged particles create an electric field, which in turn induces a magnetic field. The relative movement between the charges and the electric and magnetic fields causes the displacement of the charges and thus generates the displacement current.
The displacement current is a vector quantity, meaning it has both magnitude and direction. The magnitude of the displacement current is equal to the magnitude of the electric current, and the direction of the displacement current is the same as the direction of the electric current.
For example, when a charged particle is accelerated by an electric field, it creates an electric field that pushes other charges in the direction of the field. This motion of charges creates a magnetic field that opposes the motion of the charges. The relative movement between the charges and the electric and magnetic fields causes the displacement of the charges, generating the displacement current.
The displacement current is an important concept in electromagnetism because it plays a major role in the propagation of electromagnetic waves. It is responsible for the generation of both the electric and magnetic fields that constitute an electromagnetic wave. Additionally, the displacement current is responsible for the interaction between electromagnetic waves and conductors
