Question

electric bulb is rated 220 w and 220 V what information does it convey​

Answer 1

Answer:

An electric bulb rating is 100Watts, which means it will consume 100W power and with this parameter you can easily calculate the power consumed by the bulb per hour or per week or per month or per year.

for an example,

I’m going to say this bulb is glowing for four hour, here i want to know how many units consumed by this bulb for four hours?

The calculation is,

100W x 4H = 400WH,

1 unit is equal to 1000W or 1KWH.

400/1000 = 0.4 unit.

The 250V Indicates the operating voltage of the electric bulb and its a single phase.

Answer 2

Explanation:

It conveys that that the electric bulb must be connected too a 250 volts supply(potential difference must be 250) and it consumes a power of 100 W.

On further calculation, u will also get the amount of current and resistance offerered by it.

Hope this helps u, if yes, pls mark brainliest.
