Question

What is displacement current?

विकल्प

• The current that exists only where charge flows through a wire

• The current that exists only where the electric field is constant

• The current that exists only where a magnetic field is constant

• The current that exists at any point in space where a time-varying electric field exists

Answer 1

Displacement current exists wherever the electric field varies with time. Charge does not have to flow through that region.
