Calculating the cost of electric used for operating a TV set.?
Answer:
By multiplying the wattage consumed (usually around 100 to 150 watts depending on screen size) by the number of hours used then multiplying that result by the kilowatthour rate from you local power company. This varies quite a bit depending on the company and the time of year. For example, my power company can vary from 8 cents to 16 cents per kilowatthour depending on several variables. So if you figure 125 watts for an average of four hours per day = 500 watt hours or, .5 kilowatthours times 12 cents. Then your set would cost 6 cents per day to operate. This is insignificant when compared to an electric clothes dryer or air conditioner which can consume 10 to 15 times more power than a TV. So relax and enjoy.
Take a look at the sticker on the back of the TV and you'll see the wattage rating.
Wattage x hours per day x days of the month = Total monthly wattage consumption.
Divide that by 1000 and you get Kwh or kilowatt hours.thats what the electric company charges you by..they can charge 8 cents, 10 cents, or even 12 cents a kilowatt hour..
So a 300 Watt TV operating 6 hours a day for 30 days would be 54000 watts per month.
Divided by 1000 would be 54 kilowatt hours and at 10 cents would be $5.40 of electricity
That's pretty entertaining...
