The wattage measures an instantaneous power consumption of a load. You get charged by Watt Hours. A typical cost per 1000 watt hours might be around 12 cents.
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!
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 formula you are looking for is I = W/E. Amps = Watts/Volts.
It depends on your location.
you have to know how much voltage it is plugged into and how many amps it consumes. voltage x amps = watts. Look on the electrical plate on the back of the TV. for example in the US it might be 120 volts x 5 amps = 600 watts or .6 kilowatt hour (about 6 cents per hour). This tells you how much electricity the TV uses, not how many it has.

$350?
The formula you are looking for is, 746 watts = 1 HP.
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.
about 300:350
$250-$350
350$
350$
In Massachusetts, they cost about $600.
it cost $347 to mine and for extra info 1400 watts of energy
Well they cost about 350 to 600 dollars depending where you buy them
