(b) Temperature coefficient of resistance
The resistance of a conductor also depends on its temperature. The
resistance, for example, of pure metals increases with temperature,
and the temperature coefficient a (Greek letter alpha) is the
fractional increase of the resistance per degree increase of the
temperature, above a defined temperature ...
