| The flow of electric charge Q is referred to as an electrical current I. The amount of charge per unit time
is the change in electrical current. A current flows at a constant value I. during the time t, it transports the
charge Q = I × t. For a temporally constant power, the relationship between the charge and current: I = Q / t or Q = I × t. Through this relationship, the basic units of amps and second the Coulomb in International System of Units is set. The Coulomb unit can be represented as 1 C = 1 A × s. |
