Question

Can one have a displacement current as well as a conduction current within a conductor? Explain.

Short answer

Yes, both conduction and displacement current flow through the same conductor.

Step-by-step solution

Step 1:

The conduction current is defined by the expression dqdt, referring to the current carried by charge carriers in the wire, whereas the displacement current is generated by the time-varying electric field.

As a result, as demonstrated by the fourth Maxwell's equation, applying both the changing electric field via the conductor.

There is a conduction current density and a displacement current density when a current is induced in a conductor using an oscillating electric field.

Hence, yes, both conduction and displacement current flow through the same conductor.
