| Brill | E lectricity is produced when valence electrons are freed from atoms of conductive materials. When these electrons are set in motion in the same direction an electric current (I) is produced that is measured in amperes. Opposite charges on the ends of the conductor cause the elec-trons to flow in one direction toward the positive terminal. The differ-ence in potential between the positive and negative poles provides the electromotive force (voltage) to drive the current through the conductor (Figure 1). |
