Sources of electrical energy

This article provides information on the following six methods of producing electricity. 1. * Friction: Energy produced by rubbing two material together. 2. * Heat: Energy produced by heating the junction where two unlike metals are joined. 3. * Light: Energy produced by light being absorbed by photoelectric cells. 4. * Chemical: Energy produced by chemical reaction in a voltaic cell. 5. * Pressure: Energy produced by compressing or decompressing specific crystals. 6. * Magnetism: Energy produced in a conductor that cuts or is cut by magnetic lines of force.
