A power of 700 Watts, or 700 Joules per second, can run 700 Watts of lighting or a half-horse power electric motor. It could run up to 4-5 average TV sets, 3 tower PCs or 20 laptops. It could supply about 200 phone-chargers.
Mechanically 700 watts is also nearly one horse-power in theory. and it could lift a 70-kg mass at a speed of 1 metre per second.
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.
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).
the rule is.... run 100 watts 24/7 for 100.00/year. Your cfl will cost apx.75/year. However, while your cfl only uses 75 watts it is equivalent to apx 350 watts and produces a broad variety of colors in the spectrum making it great for growing!
Use the following formula to find the watts used. W = Amps x Volts. Divide that number by 1000. This will give you kWs. Determine how long the motor is to run and multiply this amount by the kilowatts you calculated. This will give you kW/hours. On your utility bill it will be stated how much you pay for a kW/h. Multiply that by your answer and you can estimate how much it costs you to operate the motor.

This information would be on the back of the screen. look for a number with the word WATTS after it. I would guess something between 120 and 190 watts.
It would cost $2.24 in electricity to run the computer 50 hours in a week.
A 100 horsepower electrical motor would consume 74,600 watts.

1000 watts per hour is a kilowatt hour and is usually 10 cents

Anything, as long as the sum of what you are running does not exceed 14000 watts.
2100 watts to run the refrigerator
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
