The light bulb Tungsten wire is used in electric light bulbs because it has such a high resistance that a thin piece will glow white hot. Also, tungsten doesn't burn up as fast as other metal wires, so the light bulb will last longer. Thomas Edison is credited with discovering a practical way to make electric light bulbs. Because of those advantages, AC is now the form of electricity used in homes. In conclusion DC electricity is an improvement on static electricity.
Batteries are a good source for DC power.
You can better understand these functions and how electricity flows by comparing it with the flow of water through a hose. The next topic is DC Circuits . I think this must have to do with the electrons being more loosely bound to the nucleus in the graphite atom than in the diamond atom, but I don't understand why this would be the case. Thanks for your help. In a diamond, the carbon atoms are rigidly bound in a crystalline structure.
