A 100 watt light bulb draws how much current at 100 volts?

Explanation:
Power equals voltage times current, so current equals power divided by voltage. For a 100 W bulb at 100 V, I = 100 W / 100 V = 1 ampere. That means the bulb draws about 1 A at that voltage to deliver its rated power. The other numbers would imply much different power (10 A would be 1000 W, 100 A would be 10000 W, 2 A would be 200 W), which don’t match the given rating. In real life, a bulb’s current is close to this at the rated voltage, though exact current can vary with temperature and supply conditions.
