Question

How does displacement current apply when charging a smartphone?

पर्याय

• It is net charge movement through every capacitor gap.

• It replaces the capacitors inside the charging circuit.

• It exists in the capacitors inside the charging circuit, completing the current loop.

• It prevents the electric field in every capacitor from changing.

Answer 1

Capacitors inside the charging circuit have changing electric fields. Displacement current in those capacitors completes the current loop.
