Charge

A property of some elementary particles that gives rise to an interaction between them and consequently to the host of material phenomena described as electrical It is measured in coulombs, the charge on an electron being 1.602 x 10-19 coulombs.

The amount of chemical energy stored in a battery and dischargeable as electrical energy. The departure from electrical neutrality at a point, or in a region, as by the accumulation, or deficit, of electrical particles. More electrons than normal produce a negative charge; fewer, positive charge.
