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.
What else can I help you with?
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
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!
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.
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.
Can you lose 240v but not 120v from main power line to house?
Yes, it is possible to lose 240V while still having 120V from the main power line to a house. This can occur if there is a fault or disconnection in one of the phases supplying the 240V circuit, which typically consists of two 120V lines. If one phase is lost, the 120V circuits connected to that phase will be affected, but the circuits on the other phase may still function normally. However, this situation can lead to unbalanced loads and potential issues with appliances.
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.
What type of power cord is required for a device that operates on 120V AC power?
The device that operates on 120V AC power requires a power cord with a standard 3-prong plug.
120v how much current does a 1500w resistace heater draw?
Using the formula Power = Voltage x Current, we can calculate the current: Current = Power / Voltage. Plugging in the values, we get 1500W / 120V = 12.5A. So, a 1500W resistance heater would draw 12.5A of current at 120V.
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
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.
How much power does a load drawing 15A with 120V across it consume?
The formula you are looking for is W = A x V.
How much current does a 120v 1200w hair dryer draw?
Using the formula Power = Voltage x Current, you can rearrange to solve for current: Current = Power / Voltage. Plugging in the values, the hair dryer would draw 10 amps of current (1200W / 120V).
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 amperes does a 40W fluorescent lamp draw?
A 40W fluorescent lamp typically draws around 0.33 amperes in a 120V circuit. This is calculated by dividing the power (40W) by the voltage (120V) to get the amperage.
