State the SI unit of resistance and define it 

ANSWER

Resistance is the hindrance offered by an object to the flow of current through it. Lower is the flow of current, higher is the resistance of a given material. 

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.
