How Electricity Gets Turned To Light
====Electricity comes in two forms, direct current, and alternating current. The electricity in objects is simply the flow of electrons. With direct current, the electrons move in one direction only, in an object that uses alternating current the electrons flow is constantly reversed in a cyclical manner. Alternating current is more common of the two, but direct current does exist in some objects (flashlights and car batteries for example.)Anything that is powered solely by batteries is considered a direct current device, and therefore uses electricity. Electricity has to flow in a full circuit, when flowing in a full circuit the electricity eventually produces heat (this happens very quickly.) Depending on the object a certain percent of the heat will be used to produce light. For example a standard light bulb may only use 10% of the electricity running through the bulb to produce light. Some of there objects are found in the list below. You can also click on the links under **Re****lating Pages** to find more information.====
