Electric current is the rate of flow of electric charges through a conductor and it is measured in Ampere.

What is the name given to flow of electric charge per unit time in a wire?

When does the current flow in an electric circuit?

What is the unit of electrical conductors?

What is meant by Joule's heating effect due to flow of current through a conductor?

What happens to the power dissipation if the value of electric current pasisng through a conductor of a constant resistance is doubled?

Electric current in circuit is measure by:

Electric field is the electrostatic force per unit charge acting on a vanishingly small test charge placed at that point. It is a vector quantity and the electric field inside a charged conductor is zero. Electric flux f is the total number of electric lines of force passing through a surface in a direction normal to the surface when the surface is placed inside the electric field The electric field at a point is
