Answer Posted / dilip
If we operate a 230V rated bulb on 100V the current will be
almost 2.5 time more than the 230V. So both bulbs will be
fused and none of it will glow.
P = V*i
For 100w bulb i = 100/230 = 0.4 A
For 200w bulb i = 200/230 = 0.8 A
Now voltage is reduced to 100 V , i = 100 / 100 = 1 A
i = 200 / 100 = 2 A
If we operate a 230V rated bulb on 100V the current will be
two time more than the 230V. So both bulbs will be fused
and none of it will glow.
