It depends on the local utility power company and the the neighborhood transformer taps used. It also depends on how far away the transformer is from the house. There is a voltage drop depending on the size and length of wire. It sometimes is 120v, 125v, 130v or anywhere in between. It doesn't make much difference.

What is the voltage that causes the most human deaths each year?
120 volts A/C, or some might refer to it as house current.
Can a 7000 watts generator power a house?
A 7000 watt generator us typically intended for 2 - 15 or 20 amp circuits at 120 volts or 1 - 30 amp circuit at 240 volts. When you say, "power a house," if you mean the whole house the answer is, No. You would need a generator capable of supplying a continuous 24000 watts or more to do that. But a 7000 watt generator is a nice one for powering some lights and your gas furnace blower during a power outage when properly connected. I do not know what the wattage is of an electric furnace to know if it can run one of those.
What happens when a regulator doesn't get enough volts?
A regulator loses some voltage in regulating its output, known as the dropout voltage. So the input voltage must be at least the output volts plus the dropout volts. If the input voltage is too low, the output will drop out of regulation.
Should all three phases of 3 phase motor are to be equal on no-load and load conditions?
Ideally all three phase currents will be equal. There may exist some voltage imbalance from the power source, which will result in unequal currents.
What is the energy voltage in United States houses?
I think you mean "what is the voltage of the electric power distribution in US houses" It's called 240 volt single phase, which is a misnomer, as it is actually two phases of 120 volts each. Most outlets are connected to one of those phases and supply 120 volts to appliances. Some appliances that require more power connect to both phases for 240 volts.Addendum to the answer:The answer above might look a bit vague, the voltage in the US is 120V (same as Canada, most of Europe is 220-240 V), the electrical frequency is 60 Hz. Plugs used are A or B.
Does a house plug have 115 volts or 240?
It depends which country you are in. Some countries use 115 Volts AC for household supplies, some use 220, 230 or 240 Volts AC. See the link below for a list of which countries use which voltage.
Why are some currents cold and some warm?
there are some warm currents as they flow along the earths surface while there some cold currents as they travel below the earths surface
Does every house in the UK have a house number?
Not every house is numbered in the UK. Some properties are named instead of being numbered.
What is the voltage that causes the most human deaths each year?
120 volts A/C, or some might refer to it as house current.
Why are warm currents warm and cold currents cold?
there are some warm currents as they flow along the earths surface while there some cold currents as they travel below the earths surface
Why are some density currents warm and others cold?
there are some warm currents as they flow along the earths surface while there some cold currents as they travel below the earths surface
Compare and contrast surface and density currents?
Density currents are slower than surface currents b/c surface currents are powered by the wind.
Why would all my house voltage go to 200VAC when connected to a portable generator?
Assuming you normal house voltage is 120 volts, sounds like something is wired wrong. If you had the house (or part of it) running on generator and then took some voltage readings, you may have damaged some of the items in the house already.
Can a car battery run a 120v device?
No. You'd need some fairly serious converters to go from 12 V to 120 V The above answer is 100% correct. And may I add that a battery is 12 volts DC (Direct Current) and 120 volts is AC (Alternating Current). These are two totally different currents and they do not mix.
What are some ways that ocean currents and wind are similar?
They are similar because if you think about it carefully, the ocean currents are caused by the air currents and the air currents are caused by the ocean currents, so, it is all a scientific cycle.
How many volts is a 90 amp stock alternator?
Most likely 12 volts if it is on a car. Some boats use 24 volts, or in the case of my boat 32 volts.
Why is there 208 volts?
208 volts is what is measured when looking at three phases of 120 volt electricity. In three phase electricity, rather than just providing one push of voltage, it provide three rapid pushes of electricity. This allows additional power without the danger of a higher voltage. Unfortunately because it is phased, while some currents are moving in one direction others are moving in the opposite direction. As a result you can not measure the full force the electricity at any one moment in time. The full force would normally be 360 volts [3 phases x 120 volts]. But because of the cancelling out of currents you can only measure the root mean square of the voltage at any moment in time. That would be the square root of the number of phases multiplied by the voltage [squareroot (3) x 120 volts] which equal 208 volts.
