SI unit of resistance is Ohm (Ω). It is resistance offered by an object when 1 volt potential difference is applied across it and 1 Ampere of current passes through it.
A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms. Good conductors, such as copper, have low resistance. Good insulators, such as rubber, have high resistance. Resistance causes electrical energy to be dissipated as heat.
