INTRODUCTION
During the past 100 years, electricity became more important to man as each year went by. Today,
in our homes, we depend on it for light, heat, and music. It provides power to operate water
pumps, tools, kitchen appliances, and many other household items. Outside of the home, we also
depend on electricity for many things. The family car is a good example. It uses electricity for
lights, music, heat, and to make the engine run.
