Interactions Between Electrical and Nonelectrical Systems

An electrical system is often used to drive a non-electrical system (in an electric stove, for example, electric energy is converted to heat). Interactions between electrical and non-electrical systems are often described in terms of power. Electrical power associated with a particular circuit element is the product of the current passing through the element and the voltage difference across the element.

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).
