Question

what do you mean power rating of (220v-100w) electric bulb​

Answer 1

Answer:

think of a light bulb rated at 100 Watts. This is the power rating for the bulb. It tells us how much electricity the bulb can transform into light and heat over a given amount of time. If left on for one hour, a 25-W bulb will use 25 Watt-hours (Wh) of energy.

Answer 2

The mark 100w, 220v on an electric bulb means that the bulb has a power of 100 watts and the potential difference applied across the terminals of the bulb is 220 volts. This mark can be found in each and every bulb according to the power and potential difference.
