How do you calculate the Monthly cost of using a 700 watt refrigerator that runs for 10 hours a day at a cost of 0.09 Killowatts per hour?
(700 watts) x (10 hours/day) x (30 days/month) x (1 kilowatt / 1,000 watts) =(700 x 10 x 30 / 1,000) (watt - hour - day - kilowatt / day - month - watt) =210 kilowatt-hour / monthWe're guessing that the actual cost of your electric energy is $0.09 per kilowatt-hour.(210 kilowatt-hour / month) x ($0.09 / kilowatt-hour) = $18.90 per month .
What if your refrigerator is 5.6 amps so how much does it cost you a month at 22 cents per kilowatt?
A refrigerator is not on all the time. It is controlled by a thermostat that keeps it at a certain temperature. To answer this question the total number of hours the refrigerator was actually running would have to be recorded. Knowing this information and the voltage at which the refrigerator operates a calculation could be made.
How much does a 0.4A motor cost per month?
* 0.4A * (voltage of device V) = Power in watts P1 * P1/1000 = Power in kW P2 * P2 * (electric rate in dollars per kWhr) = Cost dollars/hr C * C * (days in this month) * 24 hr/day = Cost in dollars for this month
Your welders have an input of 240 volts and draws 30 amps how much does it cost to run the welder if you weld 8 hours a day 5 days a week electricity costs 09 per kilowatt hour?
Your welder uses 240 x 30 = 7200 watts = 7.2 kilowatts. Use it constantly for 8 hours then it uses 7.2 x 8 = 57.6 kilowatt hours. The cost for this 8 hrs is 57.6 x .09 = $5.184. Multiply by 5 to get $25.92 per week.
How many kwh will a 20 watt light bulb use burning 24-7 for one month?

77000 watts for 30 days is how many kilowatt hours?
Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
How much does it cost to use a 100 watt 120 volt light bulb?
At 10 cents per kWh (Kilowatt hour), one 100 watt incandescent light bulb ran for 24 hours straight will cost 24 cents a day. $7.30 a month, $87.60 a year. kWh = (Watts Used * Hours per Day * Days per Month) / 1000 Cost per Month = kWh * Cost per kWh
How much cost to burn a 60 watt bulb 12 hours a day for 30 days?
The simple way to calculate cost is $1 per watt per year. This is based on a cost of about 11 cents per kilowatt hour. Your cost may vary. So, 60 watts times 1/2 year (12 hours /day) divided by 12 ( 1 month) equals $2.50 per month.

How do you compute electrical consumption of a device?
A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist
