Electric current

The controlled movement of electrons (or drift) through a substance is called current.

– Current is the rate at which electrons moue. One ampere (unit of current) represents 6.28 x 1018 electrons passing a point each second (1 coulomb past a point in one second).

Ampere = coulomb / second

One coulomb = charge of 6.28 x 10 18 electrons
