First let us convert the power of the bulb into kilowatts.

A kilowatt is 1000 watts. We have one tenth of that. So 100W = 0.1kW

To work out the kilowatt hours we simply multiply the power in kilowatts by the time the bulb is on for (in hours):

0.1kW x 10h = 1 kWh
a 100 watt bulb uses 100 watts of power. In ten hours it uses 100x10 watt-hours, or 1 kilowatt-hour. A kilowatt-hour is also called a unit, and units are what you pay for.

Well it depends on what light bulb it is :)


100 x 24 watt-hours, which is 2.4 kilowatt-hours.


1 megawatt = 1 million watts = 1000 kilowatts. So 1 megawatt for 1000 hours will give 1 million kilowatthours. More megawatts will give the same kilowatthours in a shorter time period.Don't forget- watts, kilowatts, megawatts are rates of energy, kilowatthours are quantities of energy. A quantity is given by a rate x a time period.


It depends what light bulb, although for a regular light bulb it takes about 2-3.



It depends how big the light bulb is to be honest


it depends,the flourecent kind hols 60 watts,lumens has 120 and they last for 10,000 hours.


No, there are many instances where a light bulb is never turned off. It is not a good principle to get into as the watt meter keeps turning and money is being spent to keep it on in daylight hours.


You wouldn't use a potato to screw in a light bulb... if the glass in the light bulb breaks as you're removing it, you can use a potato to take the light bulb out.
