8.1 Electric Potential Energy & Voltage Electrochemical cells change chemical energy into electrical energy. Connecting cells together makes batteries. The ends of batteries are terminals – connecting to them allows electrons to flow from the battery through a device that converts electric energy into other forms. (c) McGraw Hill Ryerson 2007 See pages 270 - 271

(c) McGraw Hill Ryerson 2007 Electric Energy Electric energy can do work. Electric energy that is stored = potential energy Electric energy that is moving = kinetic energy (c) McGraw Hill Ryerson 2007
