P = V2/R
If V = 220 V we have
100 W = 2202/R
R = 2202/100 Ω = 484 Ω. This is the resistance of the bulb.
When V = 110 V, power consumed = V2/R = 1102 /484 = 25 W
If V = 220 V we have
100 W = 2202/R
R = 2202/100 Ω = 484 Ω. This is the resistance of the bulb.
When V = 110 V, power consumed = V2/R = 1102 /484 = 25 W
