3.05 Electrical current.

Electrical current is a measure of the rate of flow of electrical charge through a material. Consider an electrical current flowing through a wire. The magnitude of the electrical current will depend on;

  I = naqv .

Example.

 I   =   naqv   =    2x1028m  x   2.5x10-6  x   1.6 x 10-19  x   1x 10-3    =   8 Amps
