Given V = 220 V P = 110 W
we can calculate current I=?
P = VI I = P/ V= 110/ 220 = 0.5 A
Now when V = 100 V ,then power is
P = V I = 100 × 0.5 = 50 W
then calculating current
I = P/ V 50 / 100 = 0.5A
we can calculate current I=?
P = VI I = P/ V= 110/ 220 = 0.5 A
Now when V = 100 V ,then power is
P = V I = 100 × 0.5 = 50 W
then calculating current
I = P/ V 50 / 100 = 0.5A
