Question

Name the current which can flow even in absence of electric charge

Answer 1

It can also mean charges of one coulomb (or 6.24x1018 electrons) passing through a cross-section of a conductor in one second. Electric current is flow of electrons in a conductor. The force required to make current flow through a conductor is called voltage and potential is the other term of voltage.

Answer 2

Hii friend,

This is a tricky question.

# Answer- displacement current

# Ampere Maxwell law-

The total current passing through any surface of which the closed loop is the perimeter is the sum of the conduction current and the displacement current.

There are two sources of magnetic field

1)Conduction electric current due to the flow of charges

2)Displacement current due to the rate of change of the electric field

The term displacement current was coined by J.C. Maxwell.

Hope your concept is clear now.
