Thsi depends on the light bulb specification.

For example if you buy a standard 60W light bulb from your supmarket then this will consume 0.06kilowatts.

Its simple just divide the wattage stated on the light bulb by 1000 to give you the kilowatts

Energy-saving bulbs use much less than 1 kilowatt and most of them use less than 40 watts which is 0.04 kilowatts. A 20 watt bulb uses 1 kilowatt-hour of energy if run for 50 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.

Add up all the individual watts, convert everything to kilowatts, then multiply by the number of hours.

Many objects use light such as the light bulb,the sun, a camera and many others rainbows also use light

0.04 kilowatts one kilowatt is 1000 watts

Also CFL and LED light bulbs use much less actual wattage than their equivalent wattage. It is best to look at the datasheet for each individual type of light bulb. They can vary from milliwatts to kilowatts, depending on the purpose the light bulb was intended for.

it varys from light bulb to light bulb.

It will last you a very long time depending on what you use it on. A light bulb will last you until it burns out. It is equal to what the ENIAC used.

we use the light bulb in every day life

There are light bulbs of many different voltages and power.

Multiply its power, in kilowatts, (i.e. 120/1000) by the length of time it is in use, in hours. This will tell you how much energy it has used, in kilowatt hours.

That depends on how many light bulbs are in the bathroom and how much power each of them use.

AnswerIt is my opinion is that the light bulb can be important like if it was a dark night and you wanted light. You could turn the light on (light bulb). I also think it is stupid because if the power went out you couldn't use the light bulb because you need power!AnswerThe light bulb is important because it lead to the infrastructure of electricity in society and all of the many things that we now use electricity for. The practical light bulb led the way to so many other useful inventions; it 'shed light' on what was possible.

That depends on how many volts does that bulb use not watts...

People use light bulb for luminescence in homes. It is a substance which provides light to homes.

what is the relationship of light bulb and grounding

you can use a plastic cover to cover a light bulb........if you want to cover a white light bulb,you can put a colored sheet or plastic.

Answer: It depens what type of dryer.Answer: Also, the power rating is in watts or kilowatts, not in kilowatts/hour.

In many cases, the brake light and the turn signal use the same bulb.

The only power used by a desk light is that used by the bulb. The bulb normally has its power in watts marked on it.

1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours

The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.

Depends on what light bulb you're installing
