Write shorte note on Carbon.

Carbon: The rate of commutator wear in electrical machines is greatly decreased by using brushes made of carbon. Carbon (C) is also used in automatic voltage regulators for making the pressure sensitive pile resistors. It is used for making arc welding electrodes, variable and fixed resistors for light currents and contacts of specific classes of dc switch gear that are subjected to arcing. The resistance temperature coefficient of carbon is negative.
