Conductance Described
Conductance is the ability of a material to carry electrical currents; it separates conductors such as silver and gold from insulators such as glass, plastic and rubber. Scientists and engineers use a complicated unit to measure conductance: Inverse ohms times meters, where a higher value means greater conductance. Materials with greater conductance carry more electrical currents with less voltage; this is a desirable property, because it means the material loses less electrical energy.
