185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
1500 watts... Average electric bill is $0.98/ killowatt hour (1000 watts an hour) So it wil cost around $1.50- $2.00/ Hour to operate
Watts measure power flow. To find the cost you must find the amount of energy, so to do that you multiply the watts by the time the power flows. 1 unit of electrical energy, which costs 5-25 p in the UK, is 1 kilowatt-hour, which is 1 kilowatt for 1 hour, or 1000 Watts for 1 hour, or 100 Watts for 10 hours, or 10 Watts for 100 hours. In the USA, it's different everywhere, but figure 25¢ per kilowatt-hour.
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.
Well, I pay about $0.13 for each kilowatt hour of electricity, so, at that rate it would cost between 3 and 4 cents per hour to run. If you ran the 310 watts for a year it would cost about $353 per year. Amazing how that adds up!
Electricity is sold to consumers thru meters that record kilowatt hours: 1000 watts turned on for 1 hour= 1kwh or kilowatt hour. If cost for 1 kwh = $0.10, then 1500 watts for 1 hour would cost 15 cents. Varies by location of the country. Check your utility bill for exact cost per kwh.

It would cost $2.24 in electricity to run the computer 50 hours in a week.

Convert the watts to kilowatts, multiply by the time to get the energy (in kWh), then multiply by the rate.
Great question! It depends on the size. 20 minutes = 0.66 hours. Small: 800 watts/hour 264 watts in 20 minutes Medium: 1440 watts/hour 475 watts in 20 minutes Large: 2000 watts/hour 666 watts in 20 minutes To get an idea of how much this is, in terms of cost and in comparison with other appliances, you may want to check out the related link.

A single bar of an electric fire usually consumes 1000 Watts or 1 Kilo Watt (kW) Run the bar for 1 hour and you use 1 KW/Hour (1000 Watts for 1 hour) Refer to your last electricity bill where your supplier will list their charges in KW Hrs. I would imagine around 25 cents? per Kwh
A 100 horsepower electrical motor would consume 74,600 watts.
About $10. Do the math. Amps x Volts = Watts. A typical dryer is 30 amps @ 240 volts. That's 7200 Watts. Average electricity cost is $.07 per 1000 watt-hours. So...if you run the dryer for one hour ...it will use 7200 watt-hours. 7.2 x $.07 = $.50 per hour of usage.
If we assume that you are using a 120V electric pencil sharpener, then it uses approximately 100 Watts. Over a ten hour period of constant use, that would add up to 1 kWh.
The multiple of (0.5 kw per hour) X (total hours of functioning) X (the cost of 1kw-hr).
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
