The most common residential voltage furnished in the United States is single phase, three wire, 120/240 V AC.
The utility runs two "hot legs" and a neutral to each customer. In your electrical panel, each circuit breaker creates a circuit using one 120 V wire and the common neutral. The standard three prong receptacle ("hot, neutral, and ground") is designed for a nominal 120 V plug. Nominal 120 V means anything from 110 to 125 V AC.
The two 120 volt "legs" are 180° out of phase from one another. Connecting a device across the two "hot legs" provides 240 volts. This is typically used for AC units, electric dryers, electric ranges, water heaters, and well pumps. Other residential devices that might require 240 V are hot tubs, larger air compressors, and welders.
The exact voltage ranges can vary from state to state, and will flucuate over the course of the day and your location on the distribution feeder. The laws of physics dictate that there is a voltage drop through the wires. This voltage drop is dependent on the current flowing through the wires and the distance. It is not uncommon for a utility to have a steady-state voltage window of 113 to 127 volts.
While the most common voltage is 120/240, there are other states with a nominal voltage of 115/230. It is rare for a utility to furnish 110/220 at the meter.
After the electricity enters your home, there is additional voltage drop along the wires to your receptacle. If you started at 110 at the meter, you might be down to 105 when running equipment on the other side of the house.
I found a diagram that shows the voltages "phase to phase" and "phase to neutral". Unfortunately it also has some extra numbers in parentheses. Ignore the values that appear in parentheses. (240) (480).

The standard voltage is 110 V with 60 Hz frequency.

the standard potential difference measured in volts in all 50 states is 110 volts with 60 Hz.

In USA 110 volts if you have a 230 volts take it to electrician and he can convert it to 110

It is 110 but appliance like your oven use 220.

On my side the two are better. in case you chosen 110volt potential would be saved. this is going to offer much less marvel. in case you chosen 230volt much less no of issues would be used.turn away of 110v is that potential produced would be low and in case you chosen 210v you will get severe electric powered marvel.
