To calculate the cost of running a 1000-watt device for 12 hours, you need to know your electricity rate per kilowatt-hour (kWh). Multiply the device’s wattage by the hours of use, then divide by 1000 to get the total kilowatt-hours used. Finally, multiply the kilowatt-hours by your electricity rate to get the cost.
If the transformer uses 5 watts per hour you need to know what you are paying per 1000 watts from your power company. If you pay lets say $3.00 for 1000 watts then when your transformer burns 1000 watts it cost you $3.00 your cost will be $3.00 for 200 hours run time.
The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
To calculate the cost of running a device that consumes 185 watts per day, you need to know the cost of electricity per kilowatt-hour. Assuming an average cost of $0.12 per kWh, running a 185-watt device for 24 hours a day would cost about $0.50 per day (185 watts / 1000 * 24 hours * $0.12).
Two formulas are needed to calculate the answer:[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]and[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?

60 (watts) x 12 (hours on) x 30 (days per month) = 21600 (watt-hours) 21600 / 1000 = 21.6 killowatt hours X your electric providers price = $$$

It would cost $2.24 in electricity to run the computer 50 hours in a week.
It depends on the bulb, how many watts it is. All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity. Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.
Two formulas are needed to calculate the answer:[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]and[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?
To calculate the cost of running a 5.8 amp motor at 120 volts, you need to know the cost per kilowatt-hour (kWh) of electricity. Multiply the motor's amperage by the voltage to get the power consumption in watts (5.8 amps x 120 volts = 696 watts). Then divide the watts by 1000 to convert to kilowatts (696 watts / 1000 = 0.696 kWh). Finally, multiply the kWh by the cost per kWh to determine the running cost.
Pumps don't have wattage but the motors that drive them do. motors are rated in amps and volts. if you multiply amps times volts you get watts. Gallons per hour are listed on pumps or can be measured by running the pump for a calculated time and measuring the gallons. Run the pump 1 min and measure the water and multiply by 60 and you have gallons per hour. A kilowatt/hour is the equivalent of using 1000 watts for one hour, 100 watts for 10 hours, or even one watt for 1000 hours. Any combination of watts times hours that equals 1000, is one kilowatt/hour's worth of power used. (Wiki)
40 watts for 24 hours is 40 x 24 watt-hours, or 960 watt hours which is 0.96 kilowatt-hours, equal to 0.96 Unit, which costs about £0.12.
A standard cartridge heater usually requires between 1000 and 11,500 watts to run. They run on 120 or 240 volts and one can find more information on the Chromalox website.
