How many appliances can be used in 3.5kwh?
The number of appliances that can be used in 3.5 kWh depends on the energy consumption of each appliance. To calculate, divide 3.5 kWh by the average energy consumption of each appliance in kWh to determine how many can be used.
How much does a 110 volt 12 amp appliance cost per month with 9 cents per kWh?
Use this formula to arrive at the wattage used. W = A x V. Now figure out how many hours there are in a month. Days (30 or 31) x 24 (or the number of hours the appliance is on per day) will give you this answer. Take that answer and multiply it by 9 cents or .09 for your answer.
Calculate electricity usage?
Watts x hours/1000 = Kwh Kwh x your electricity cost ($/Kwh) = $ For example: If you run a 60 watt light bulb for 8 hours and your electricity rate is $0.12/Kwh: 60 x 8 / 1000 = 0.48 Kwh x $0.12 $/Kwh = $0.576, or about 6 cents. This calculation works for any appliance, the watt usage is usually listed on the appliance
How do you work out total cost of 35kwh to cost per kwh?
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate the kWh consumed by a 3-phase motor, you'll need to know both the power factor and operating hours. The formula is: kWh = (√3 x Volts x Amps x Power Factor x Hours) / 1,000. Without the power factor and hours of operation, a precise kWh calculation cannot be provided using just voltage and current.

What is the equation to find the amount of energy used. By appliance?
The equation to calculate the amount of energy used by an appliance is: Energy (kWh) = Power (kW) x Time (hours). Multiply the power consumption of the appliance in kilowatts by the number of hours it's used to find the total energy consumed in kilowatt-hours.

How do you calculate the monthly running costs of electrical appliances?
When you get your electric bill, look to see how many kilo watt hours (kWh) you used for the month. Then how much the bill cost. take the price divided by the (kWh). This is truly what your paying per (kWh). One (kWh) is 1000 watts being used for a hour, so one 100 watt light being used for 10 hours = 1 (kWh) or a 1500 watt hair dryer being used for an hour = 1.5 (kWh). so if your appliance power use is listed in amps, take amps x volts to figure out the watts. Plus determine how often the appliance runs. this will give You an idea of cost.
How do you calculate running cost using kwh?
First find how many kw are being used. For example, two items using 0.5 kw each add to 1 kw. Then, multiply by the hours it is being used. If we ran these two items for 1 hour we would end up with 1 kwh.
How many KWh does a clothes dryer use?
None if your plugged in to the neighbors electricity!!
How do you work out total cost of 35kwh to cost per kwh?
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
How you calculate import Kvarh in percentage?
P.F = Kwh/Kvarh
How many kWh in a cubic meter of water?
kWh stands for kiloWatthours, the amount of electrical energy an appliance uses or generates in one hour measured in kiloWatts. It has nothing to do with one cubic metre of water.
How much power is in a 120V line?
Most 120 Volt appliances have their Watts listed somewhere on the appliance. Divide this number by 1,000 to get kilowatts. Determine the rate you are charged for electric power. Your electric bill will tell you how many kWh(kilowatt hours) you use, and what the total charge is. Divide your total charge ($?) by the kWh used. In northern Illinois, we are charged about $0.11 per kWh. Multiply the number of hours the appliance is used by its power consumption in kilowatts. This gives you the number of kWh the appliance used. Then multiply that kWh value by the rate for your area that you determined from your electric bill. That will be the cost for the number of hours the appliance was on. Example: If I toast 2 slices of bread in my toaster, it takes about 3 minutes, or 0.05 hours. My electric bill is $61.38 and I used 558 kwh for that month. Dividing $61.38 by 558, I get about $0.11 per kWh. So, I divide my toaster Wattage (750) by 1,000 to get 0.75 kW. So now I can multiply the hours that the appliance was used (0.05) by its power consumption rate in kW (0.75). This result is 0.0375 kWh of energy used. Then I can multiply the rate the electric company charges ($0.11) by the energy used (0.0375 kWh). The final result is $0.004125.
