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.

If you have low voltage lights in your yard and you want to install a decorative street lamp how do you increase the voltage to power the 120V street lamp?
you don't run a new 120 line
Can you take single phase of 120V with a hot wire and a neutral step up to 480v and then step down to 2 phases of 120V or do you have to input 2 phases of 120v to get 240V out?
Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
What will happen when the shunt motor is connected across the supply line directly?
If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
What are the dangers from hitting a power line while digging?
When digging it's possible to hit an underground power line. Hitting an underground power line can be very dangerous and is similar to having contact with an overhead line.
Where can you find a 120V power cable?
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
The motor states 120v single phase to operate.can you use it using 230v supply in Singapore?
Absolutely not. In the U.S. all power is 120v on a single line (one hot, one neutral, one ground) overseas all power is 230v on a single line. Will fry your unit. You can however by a step down or up transformer fairly cheaply at radio shack.
In a home has 120v service there is an electric appliance that a risistance of 12 how much power will this appliance consume?
1440 Watts
How much power does a load drawing 15A with 120V across it consume?
The formula you are looking for is W = A x V.
Can you plug two appliances a 120v and a 110v on the same line which is a 110v?
Should be ok provided you do not draw too much current.
Can I use 120v 10a 1250 w cable for projector 110-240v power in India?
You can use 120v 10a 125w cable projectors 110-240v power in India.
If you have low voltage lights in your yard and you want to install a decorative street lamp how do you increase the voltage to power the 120V street lamp?
you don't run a new 120 line
How much power does a microwave oven use if it has a current of 5.8A and a voltage of 120V?
5.8 amps x 120 volts = 696 watts
How much voltage does a line with resistance of 10 ohms and a current of 20 amps?
V = i*r v = 2 * 60 v= 120v
What is the standard power of apc 1500?
The APC 1500 has a standard power of 865 watts/1500 VA. The APC 1500 has an output of 120V and an output of 120v. The specifics of the model can be found on the official website.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
If you had 277-480 3phase power feed can you still use it to power IT equipment rated at 110-120V?
yes
