Energy suppliers of electricity and natural gas will give you a cost per kilowatthour, and your usage is metered. With coal you buy it by the ton, so you need to know how many BTU that grade of coal will give per ton. With oil, the energy content of that type of petroleum product should be available from the supplier, per gallon or 100 gallons probably. You would have to keep a check on how much you are using over a period.

The cost will surely vary from one country to another. Look at your electricity bill, and divide the total cost by the number of kWh you have been charged. That will give you the cost per kWh.

it is either c=rt or c=pt

cost= rate * time or

cost = power * time

(help me please)

<<>>

Energy is power times time, the cost is energy times the rate.

example: a 100 watt bulb run for 24 hours uses 100x24 watt-hours or 2.4 kilowatt-hours (units) of energy. At a rate of £0.15 per unit the cost is 2.4 x £0.15 or £0.36.

It depends entirely upon what type of energy, where you are, when the energy is being used, and what type of system you have to use it. All of these things affect pricing.

<<>> Power is measured in watts, while energy is measured in watt-hours or kilowatt-hours, among other things. The power (watts) tells you how fast energy is being used, then that is multiplied by the time to find the energy and the cost.

If a 1 watt load (a bulb or anything else) runs for 1000 hours, that represents the same amount of energy as 1000 watts running for 1 hour and that is a kilowatt-hour, also called a Unit, costing 10-15 p or cents.

How much energy will it take to produce one watt of power in one second?

1 watt means 1 joule/second. To produce 1 watt means that every second, 1 joule of energy is produced.


How much does 1 volt of electricity cost?

Electricity is not sold by the volt. It is sold by the watt, a unit of power. One watt equals one volt-ampere.


Does one watt is the work or energy required to produce one watt of power in one second?

No. One watt is one joule/second.


How much does a 60 watt light bulb use per hour?

Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 cents.


What is 1 watt of power?

One Watt is one Joule of energy transfered every second. So the Watt is the unit of enegery transfer.


How much does it cost to run Watts?

A Watt has no cost all by itself because a Watt is a unit which is used to measure a rate of using energy. Energy has to be supplied to equipment at a certain rate to make it do the work it was designed to do. Another way of saying the same thing is that something that does work needs to use energy at a certain rate. The equipment could be an electric motor, a light bulb etc. The equipment does not even have to be powered by electricity. If it was, say, a bicycle pedalled by a human being, it might need to be given one Watt of energy in a second to move it one yard of distance on a level road, or it may need 10 Watts of energy over 10 seconds to move it 100 yards. Depending on the steepness of the hill, it might need to be given 1000 Watts of energy (= 1 kiloWatt) to move it 100 yards up a slope in 10 seconds. Saying something "takes one Watt" is like saying "A person can eat one apple in a minute." It would not cost you anything to buy the apples until the person started eating and then it would cost you the price of one apple every minute or 60 apples every hour, for as long as the apples are being eaten. So, when you calculate the cost of supplying energy, you always have to reckon-in the time over which the energy units (Watts) are being used as well as the amount of Watts taken. Most electricity is charged by the kiloWatt-Hour (kWh is the usual term) So 1 Watt-Hour would cost 1 thousandth of the price of a kiloWatt-Hour. You can find the local price of a kiloWatt-Hour of electric power in any electricity bill.


What is one joule of energy transformed in one second called?

That is called a Watt. The Watt is a unit of power.


Work or energy required to produce one watt of power in one second?

You have all the right words, but the concept is backwards. Energy is the amount, power is the rate of energy. One watt of power is required to move one joule of energy in one second.


How does watt and joule relate?

The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.


How long is a watt hour?

A watt hour is a unit of energy, not time -so you cannot ask how 'long' it is. The time taken to consume a watt hour of energy depends upon the rate (i.e. the power) at which it is consumed, expressed in watts. A watt hour is defined as the amount of energy consumed, over a period of one hour, at the rate of one watt.


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.
