Converting 14 watts to kilowatts: 14 watts x (1 kilowatt / 1000 watts) = 0.014 kilowatt. Your energy consumption for one (1) hour is 0.014 kilowatt x 1 hr, this is equal to 0.014 kilowatthour. Cost for energy consumption: 0.014 kilowatthour X (20.52 cents / kilowatthour) : 0.28728 cents only

∙ 9y ago60 watts for one hour is 60 watt-hours which is 0.06 kWh. Therefore the cost is 0.06 x 11.4 cents.

∙ 11y agoA 1-watt bulb uses 3600 watt-hours every hour, which is 1/1000 of a kilowatt-hour, so the cost is 0.01 cents.

How much does it cost to run a 60 watt light bulb for 1 hour if electricity costs 10 cent per kilowatt-hour?
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
How much electricity costs when a light bulb is on for a long period of time?
It depends on variables. The amount your supplier charges per kilowatt. The wattage of the lamp. and how long it is left on.
How much money does it take for the electricity of an incandescent light bulb use?
You are charged by Kilowatt Hours. An average cost is about 12 cents. To make the math easy, assume a standard 100 watt incandescent bulb. If you had ten of them turned on for an hour it would cost 12 cents.
How much does it cost to run a 1000 watt light bulb in 12 hours?
Well lets see, 40 watts for 1 hour is equivalent to 0.04 KWh. Average electric costs is roughly 18 cents per KWh so 0.04KWh would cost 0.72 cents ($0.0072).
How much does one kilowatt cost?
Well if you think about it you can't really sell electricity so therefor it dosent really have a price but I'm pretty sure you weren't going to try and stik it in a bottle and sell it right
How do you compute electrical consumption of a device?
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

What is one half kilowatt of electricity?
A kilowatt by definition is the equivalent of "1,000 watts for one hour". It is the way the electric company measures power usage. One "half kilowatt": Imagine you have five 100W light bulbs burning in various places in your house. After one hour, you have used one-half kilowatt of electricity.

How much electricity load you can drive on 1 kilowatt?
You could power ten 100 watt light bulbs.
How many watts does a 60w light bulb consume in a day - in pound sterling?
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.
Are kilo watt hours bad for energy?
No, kilowatt-hours are an exact measure of a quantity of energy. Energy is something that can be measured exactly and if you have an electricity supply at your house there is a meter that measures the kilowatt-hours you use. If you have a 40-watt light, it uses 40 watt-hours if it is on for an hour. If it is left on for 24 hours it uses 40 x 24 watt-hours, which is 0.96 kilowatt-hours, that might cost you 10-20 cents or pence.
What was the name of the light bulb from the electricity commercials for kids?
I believe you're thinking of Reddy Kilowatt. There is a web page at http://www.reddykilowatt.org/
