Volts Alternating Current, range from a transformer and sometimes the distance of the transformer providing the volts may cause a range anywhere from 110vac to 130 volts alternating current. as long as you are within this range what ever you have should run with what voltage is provided. Yes it is all the same, it just varies.

Yes. It's functionally the same.

Yes, 115V 60Hz will work in a 120V 60Hz power supply.


In the US, standard household receptacles are 120V, but historically they used to be called 110V. So the two are the same thing - at least in the US. Depending on the age of the electrical device the nameplate may say: 110v 115v 117v 120v and they all are referring to a standard household receptacle.

I would say yes.. household power in the US is 110 to 120V depending on location from sub station most devices are set up to operate anywhere in this range

You should have no problem as long as the pug fits into the outlet. Common house hold voltages range up to 120V.

For residential service 110V, 115V, 117V, 120V, and 125V are all functionally the same. Electric companies have been slowly increasing the line voltage over the last 100 years to cope with increased loads. That is where these different voltages come from. The tolerance is generally +/-10%. That's +/- 11.5 volts in this case. So, a 115VAC appliance will run between 103.5 and 126.5VAC. The short answer is yes. 110V appliances can work with up to 130V without being burnt, additionally, 220V appliances can work with up to 240V without being burnt.

Yes, not common practice though.

Further explain "shuts off frequently". Is the breaker tripping? Is it the normal on/off cycling an AC does? Do you have to do something special to make it come back on? FYI: 115, 110, 120...they're all the same (so to speak). 117 Volts is the target voltage.

Yes, but it may draw too much current for the circuit. If it's a 15 amp circuit and the welder draws 17 amps, it won't work. Voltage is only a part of the puzzle.

In the United States the common house current is commonly referred to as either 115 volts or 120 volts. The voltage varies due to the distance from the transformer on the pole because electricity loses voltage the further it has to travel.

The combination will have a resistance of 100ohms, and will drew 144watts. But, the wall outlet will usually be fluctuating from 115V to 135V, 120V is't only a "reference". I suggest you measure it a voltmeter before doing any calculation. Then, you can use this formula (ohms law) to find the correct answer : R = V/I In our case : R(ohms) = 120V / 1.2A R = 100ohms

yes ofcourse they both are the same

Yes, as long as the amp rating is the same. Examples, 600v 100amp fuse can be used in a 120v 100 amp's location.

No, a room air condition rated for 115v 60hz will not operate on 220v 50hz.

RMS*SQRT(2)=V(peak)or115V*1.414= 162.63V(peak)Source: What_is_the_conversion_for_rms_voltage_to_peak_to_peak_voltage

Does this air conditioner require 220 volts?

It is not uncommon to find ratings on appliances of 110v,115v,120v,125v depending on where it was manufactured. Typically these ratings allow a tolerance of + or- 10%, meaning an appliance with a 110v rating may be plugged into a source that provides between 99v and 121v.

yes, as long as the wattage are almost the same which is similar to the same current

p = v * i 75w = 120v * i i = 75w / 120v i = .625A v = i * R 120V = .625A * R R = 120V / .625A R = 192 ohm

In the US, it is between 110V Min and 120v Max

No, they are one and the same. I'm not an expert electrician but I do a lot of handy work around my house and local businesses. 110v, 115v, 120v and 125v are all the same. It has to do with voltage drops and increases due to supply and demand over varying distances from the power plant. Don't worry about the technical aspects of it all. In the same manner, 220v, 230v, 240v, and 250v are all the same also, just double of the original 110v. You probably shouldn't see 230v and 250v very much though. No biggie, whatever, all the 100's are the same and all the 200's are the same.
