120/240 volts at 60 cycles per second ac.
It is supplied as a single phase service, split 120V-0-120V.
One hot leg is 120 volts, a second hot leg 120 volts but running at 180 degrees out of phase from the first leg, and a neutral.
Every 120 volt outlet in your home carries one leg of 120 volts plus the neutral.
If the outlet has a ground, this is for safety in case there is a fault like a short of a hot leg to the internal frame or the outer casing of the appliance, which should always be connected to the ground. If such a fault occurs, the ground wire takes a very high current which causes the circuit breaker to trip or a fuse to blow.
An appliance such as a clothes dryer in your home, that uses 240 volts, is using both hot legs. Because they are 180 degrees out of phase from each other, the combined voltage is 240 volts.

The voltage of a standard US power outlet is 120 volts. It is different than the 230 volts that is used in many other countries around the world such as the UK.
110v used in us
110 Volts.
Electrical voltage can be changed by a transformer.
If you are referring to domestic electrical outlets, most regions use either 110 - 120 volts or 230 - 240 volts.
Theoretically there is no limit to the voltage of an electrical current.
Voltage is a measure of electrical potential. I understood voltage best when my first semester Electronics professor told the class that voltage is to an electrical circuit as water pressure is to a plumbing "circuit".
The Volt
Yes. In the United States, standard household voltage is 120VAC @ 60Hz. If properly installed, you can also run standard devices at 220 or 240 volts AC in the US.
Zero Voltage switching is a standard used to describe electrical appliances which turn on or off only when the output voltage is Zero.
No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.

India's voltage is 230V so you need one that will convert from that to US standard.
Input would be 120v at 60hz. Standard US wall power.
Hong Kong uses the same British Standard BS 1363 (220 Volt, 50 Hertz) electrical system used in the UK.
The voltage your computer's power supply receives depends mainly on the standard electrical service delivered into homes, offices and factories by the national electrical grid in your country.Just a few examples: if you live in North America, that voltage is 120 volts but, if you live in, say, Europe or Australia, that voltage is 230 volts.More detailsThe voltages a power supply was designed to use depends on how old it is. Early power supplies were designed to use only one voltage: the standard voltage of the electrical service delivered by a country's national electrical grid for use by small appliances in homes, offices and factories .Since the invention of the personal computer most standard power supplies have been designed to operate on a wide range of voltages. (Such as from 100 volts to 250 volts.)

American Samoa follows the American standard 110 VAC. So, generally alomsot every product from the US would work in American Samoa.The voltage in American Samoa is 120 V @60 HZ. American Samoa uses plugs A or B or F or I. Compatible with the US and Canada. Source: voltageplugregion.com
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
