WebThe 25 W lamp has a higher resistence. Because P = V 2/ R ans hence Power is inversely proportional to the resistence. So P= V 2 /R. if V is same for both. P∝1/R. Hence if the power is halved the resistence is doubled. Thus, ratio of resistence of 50W lamp to 25 W lamp is 1:2. Suggest Corrections.
