Charges and Their Motion in Materials

Electrical Basics

ll electrical principles rely on the concept of electrical charge, or simply charge. The concept of charge is based on the observation that some bodies exert non-gravitational forces on one another when they are placed close together. Like gravity, this force acts at a distance; but unlike gravity, the bodies can either attract or repel each other (gravity only attracts masses to one another).
