Question

Differentiate between conduction current and displacement current.

Answer 1

Conduction current (Ic)	Displacement current (Id)
It is produced by the actual flow of electrons in a conductor.	It is produced by a time-varying electric field (i.e., a time-varying electric flux).
It exists only in conducting materials like wires.	It exists in insulators or even in a vacuum (the space between the capacitor plates).
It is expressed as, Ic = `(dq)/dt`	It is expressed as, Id = `epsilon_0 (d Phi_E)/dt`
