Batteries are typically a few volts, the outlets in your home produce 120 volts, and power lines can be as high as hundreds of thousands of volts. A motorcycle battery, for example, is small and would not be very successful in replacing the much larger car battery, yet each has the same voltage.
Two of the most familiar aspects of electricity are its energy and voltage. But energy and voltage are not the same thing.

But energy and voltage are not the same thing. In this chapter, we shall examine the relationship between voltage and electrical energy and begin to explore some of the many applications of electricity.
