A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.

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

A light bulb turns electricity into visible illumination, usually by heating a filament or gas within the bulb.

A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.

The electricity passing through the wire filament in the bulb causes it to heat up so much that it glows brightly.

It depends on variables. The amount your supplier charges per kilowatt. The wattage of the lamp. and how long it is left on.

1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent

(100 W) x (10 hours) = (1 Kilowatt-Hour) x (14Â¢/KWH) = 14Â¢

A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist

electricity because a light bulb needs electricity

A kilowatt is 1,000 watts. A 60 watt bulb uses 60 watts in an hour. So, in half an hour it uses 30 watts. Now if a kilowatt costs 20 cents, what does 0.03 kilowatt cost?

The power in watts should be marked on the bulb. If a bulb is 20 watts, it will use 20 kilowatt hours in 1000 hours of being switched on.

A 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.

no

If your electricity costs 10 cents per kilowatt-hour, it would be about 0.6 of a cent per hour, or about 14.4 cents per day.
