What's A Watt?

A current of electricity flowing through a wire is like a stream of water flowing through a pipe. And the pressure of the water, the speed with which it flows, we call the volts or the voltage of electricity. And tfle Slze of the stream of water In the one'or two-inch pipe Is amperes when we measure the size of an electric current. But the actual volume of water that Is flowing through the pipe is so many gallons, while with electricity we measure In watts—so many watts for an hour or so many watt-hours.
