We all know how to flip a switch and turn on a light, but how do we typically measure that electric power?

Named in honor of James Watt, the inventor of the steam engine, a watt is the unit of electrical power equal to 1 ampere under the pressure of 1 volt. 1,000,000 watts is called a megawatt and is used to denote how much electricity is needed by large towns or cities.
