An electric bulb of power rating 100w - 200v is connected to a source of 100v. find the power consumed.
answer plssssss

Answer:
Explanation:
Indeterminate.
If it’s a modern LED, either it won’t work, or it might draw double the current and still draw 100W.
If it’s a fluorescent bulb, it probably won’t light.
If it’s an incandescent bulb, the resistance of the filament rises with temperature, so with less voltage and hence less power the filament will be cooler, so the bulb will draw more current and power than Ohm’s Law would suggest. Something like 35W maybe. Do the experiment.
