power consumed with a supply potential V1 is (V1/V)² × P.
P is the power and V is the potential of any device. so, resistance of that device would be R = V²/P
now, power consumed with a supply of potential V1 is , P' = V1²/R
= V1²/(V²)/P
= (V1/V)² × P
hence, power consumed with a supply potential V1 is (V1/V)² × P
