For the most part, they cost about the same. For instance, if you look up a 120V, 2hp electric motor in a catalog, you will find it draws about 18A. 120V * 18A = 2160 watts. If you look up a 240V, 2hp motor, it will draw about 9A. 240V * 9A = 2160 watts. Watts are watts. Watts are what you pay for. It takes a certain amount of power to perform a particular task, irregardless of the voltage supply. You typically see larger loads, such as a dryer, range or AC unit fed from 240V. This is because the lower current draw permits you to run smaller wire, which is less expensive to install.

A 120 volt appliance requires 15 amps to operate - what is the resistance of the appliance?
For calculation purposes R = E/I. R = 120/15. R = 8 ohms. This is hypothetical because of the internal components that make up most appliances.
Can you run a bar fridge on a 650 w generator?
Yes, as long as the bar fridge wattage is less than 650 W
Does a 6 amp 240 volt appliance hook up to 110?
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
What is the amperage of the European electrical power systems versus that of North America?
In Europe, 230 V is the normal domestic supply whereas in the US it is 120 V. For an appliance of a certain power rating, the current taken will be inversely related to the voltage, by Ohm's Law, ie power = volts x amps. So the current at 230 V will be in the ratio 120/230 of that taken at 120 V
What happens if you wire 120 volts to the 277 volt tap on a multi tap ballast?
Operating at half the required voltage, the lamp will not operate at full capacity if it comes on at all.
If a 120 volt appliance reqires 15amps to operate what is the resistance of the appliance?
The formula you are looking for is R = E/I.
Can you plug a 115V appliance into a 110V outlet?
Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.

Can a 120 volt appliance run on a 110 volt circuit?
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
What is better to run an appliance on 120 volts or 240 volts and what is the least cost to run.?
It is best to run the appliance at the voltage for which it was designed. Frequently Stoves, Clothes dryers, Air conditioners, Heaters, and a few other appliances with their own circuits run on 240. Most household appliances that are plugged in run on 120. Outside of Baltimore, Maryland, one subdivision heated houses with 480 volts. One man worked on his own heater. He was electrocuted. What he did would have caused a spark with 120 volts, not an electrocution. Higher voltage usually costs less to run if the appliance is designed for higher voltage.
Can you plug 120 vac to 240 watts?
'Voltage' is electromotive force, and the 'Watt' is a unit of power. You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.
What voltage does an inducer operate on?
A 120 volt is the inducer operate. This is what runs home appliances.
Which will do less damage between plugging a 110-volts appliance into a 220-volts circuit or plugging a 220-volts appliance into a 110-volt circuit?
You will have trouble plugging a 220 volt appliance into a 110 volt outlet because both have different polarities for the plug and receptacle that make it impossible for that action to happen.Altering the plug isn't too good of an idea, as the voltage demand of the appliance would be too heavy for the wiring.
Which is cheaper 230 wolt or 120 volt?
THE COST OF THE POWER IS THE SAME FROM THE UTILITIES PERSPECTIVE. IF YOU ARE REFFERING TO EQUIPMENT, THE 240 EQUIPMENT IS SLIGHTLY LESS COSTLY TO OPERATE, IF YOU LOOK AT THE MOTOR NAME PLATE RATING LABEL OF A MULTI-VOLTAGE MOTOR, YOU WILL FIND THAT THE CURRENT (AMPS) WILL BE ABOUT 1/2 AT 240 VOLTS THE MOTOR AMPS OF THE SAME UNIT AT 120 VOLTS.

What is 10 percent off of 130?
10% of 130 is (.10)(130) = 13 So, a bicycle that costs $130 with a 10% discount would cost $120. * * * * * No it would not. It would cost $13 less than $130, which is $117 NOT $120!
About how much does a Fisher Price swing cost?
A Fisher Price swing costs between $ 120 and $ 150, on average. Some cost a little bit more and some cost a little less.
Is a 120volt appliance safe in a 110volt step down transformer?
The supply voltage in the US and Canada has a nominal value of 120 V, but national standards allow a variation of +/-5%, so the actual voltage could fluctuate between 114 V and 126 V. If you assume a similar variation to the voltage output from your transformer , then the two voltage variations would overlap. In other words, yes, it should be quite safe for your 120-V appliance to operate from a transformer supplying 110 V.
