A light bulb consumes 19800 watt-hours in 5 days and 12 hours How many watt-hours does it consume per day?
5 days 12 hours = 5.5 days19,800 / 5.5 = 3,600 watt-hours per day = 150 watts
How many hours in 306 days?
1 day = 24 hours 2 days = 48 hours 3 days = 72 hours 4 days = 96 hours . . . 306 days = 7,344 hours
How many days are equivalent to 80 hours?
There are 24 hours in a day. 80 hours * (1 day/24 hours) = 3.33 days 0.33 days * 24 hours = 7.92 hours 80 hours is equivalent to about 3.3 days, or 3 days and 8 hours.
How many days is 305 hours?
1 day = 24 hours 305 hours = 305 / 24 days = 12 days 17 hours ~= 12.71 days.
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
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 .

A 100 watt light bulb left on for 24hrs how many kilowatts does it draw in a thirty day period?
1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours
If a 100 w light bulb is lit for 8 hours each day for W days in a month many kilowatt-hours will the bulb consume?
Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
How much is a killa watt?
1 kilowatt is equivalent to 1000 watts of energy, the average appliance will consume about 52 watts of energy. there for with the power of 200 kilowatts one would have enough power to reach mars in roughly 39 days
Watt-hour a light bulb consumes 3600 watt-hours per day How many watt-hours does it consume in 4 days and 6 hours?
-9900
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.
Why do electricity meters use kilowatt hour?
The way that watts are calculated is volts x amps. Watts will be the result of any voltage x any amperage. It doesn't matter what the countries voltage is, the wattage is constant. Amps x volts over the hours will become very large so the number is divided by 1000 to keep the number compact. Using this number it is referred to as a kilowatt. The utility company sells power a a set price per kilowatt over a one hour time interval. In my area the charge is .07 cents for every kilowatt of power that gets used.Additional AnswerElectricity meters measure the amount of energy you consume, expressed in kilowatt hours for historical/traditional reasons. These days, with the widespread use of the SI system, it would make more sense to measure electrical energy in kilojoules or megajoules, enabling one to accurately compare the cost of electrical energy with other forms of energy, such as gas.
If you run a 100 W light bulb for 30 days continuously how many Joules of energy have been used?
100 watts = 0.1 kilowatts. 0.1 kilowatts for 24 hours a day for 30 days is 0.1 x 24 x 30 = 72 kilowatt-hours.1kWh (one kilowatt-hour) is 3.6 MegaJoules of energy. 3.6 x 72 = 259.2 MegaJoules of energy used.(This is assuming a pure, constant, clean flow of electricity, it's an incandescent bulb with no power factor or electronic ballast/transformer efficiency to take into account!)
How much to operate a mercury vapor light?
As with any other light bulb or other appliance, it depends on how many watts you use. Since your electric bill is predicated on how many kilowatt hours you use, an example would be the mercury vapor lamp is 1500 watts, and you use it for six hours a day for 20 days... for each hour you use it, the cost is 1.5kW X whatever the utility charges you X the number of hrs, which in this case is 120hrs.
How many watts per year?
Watts is the product of amps times volts. As you can see this combination could have lots of variables depending on the different voltages that are in use and the variable amperage's of multiply loads. To find watts per year you would first have to find the wattage of the device, then extend it to watts per hour if the device is continually on. Then take this figure times 24 hours in a day and then finally times 365 for the days in a year. This will give you the answer that you are looking for.Alternate answer: The question is fundamentally meaningless. A watt is a measure of energy per unit time. An appliance that uses 60 watts, will use 60 watts in a second, 60 watts in a minute, 60 watts in an hour, or 60 watts in a century. Total energy can be expressed in units like "kilowatt-hours" (equal to 1,000 watts for one hour, or 100 watts for 10 hours, etc.). Our 60-watt appliance, left on continuously, will use about 525 kWh per year.
