circuits. The most common conductor materials used in electrical work are copper and aluminum. All materials possess, in varying degrees, a property referred to as conductance. Good conductors, such as silver and copper, have high values of conductance. Poor conductors or insulators, such as rubber and glass, have very low values of conductance.
