Power = V^2/R
Power is inversely proportional to the resistance
P1/P2 = R2/R1
50/25 = R2/R1
R2/R1 = 2
R2 = 2(R1).
So the bulb with 50W power has 2 times less resistance than the bulb with 25W power
Power is inversely proportional to the resistance
P1/P2 = R2/R1
50/25 = R2/R1
R2/R1 = 2
R2 = 2(R1).
So the bulb with 50W power has 2 times less resistance than the bulb with 25W power
