1. A unit of measurement of force, or pressure, in an electrical circuit.

The common voltage of an AC power line is 120 volts of alternating current (alternating directions) while common voltages within a computer are from 3 to 12 volts of direct current (one direction only).

2. The unit of potential difference or electromotive force in the meter-kilogram-second system, equal to the potential difference between two points for which one coulomb of electricity will do one joule of work in going from one point to the other.

Electric potential is the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Typically, the reference point is the earth, although any point beyond the influence of the electric field charge can be used.

3. A standard unit of potential difference or electromotive force equivalent to the potential difference between two points requiring one joule of work to move one coulomb of electricity from the point of lower potential to the point of higher potential. 4. A unit of electrical force equal to that amount of electromotive force that will cause a steady current of one ampere to flow through a resistance of one ohm.
5. The standard unit used to measure how strongly an electrical current is sent around an electrical system.

The potential difference necessary to produce a current of one ampere through an electric circuit with a resistance of one ohm (unit of electrical resistance): Because the production of absolute current and voltage must equal mechanical power, experiments that realize the absolute volt involve mechanical effects and are inherently difficult, usually requiring many years to complete.

1. A unit of energy equal to the energy acquired by an electron falling through a potential difference of one volt.
2. A unit of energy defined as the kinetic energy acquired by an electron that is accelerated through a potential difference of one volt; equivalent to 1.6022 x 10^-19 joules.
3. A unit of energy used in atomic and nuclear physics, equal to the energy gained by an electron.
4. A unit of electrical energy used in nuclear physics.

It is equal to the energy gained by an electron when it moves from one point to a point higher in potential by one volt and it is a unit of energy or work, not of voltage.

An instrument that employs the characteristics of an electron-tune or a semiconductor circuit for the measurement of voltage and resistance on a single-calibrated scale.

A unit of energy, used primarily in high-energy physics of one thousand million or one billion electron volts.

A unit of energy commonly used in nuclear and particle physics, equal to the energy acquired by an electron in falling through a potential of 1,000,000 volts.

1. A unit for expressing the integral of apparent power over time, equal to the product of 1 volt-ampere and 1 hour, or to 3600 joules.
2. A unit for the integral of apparent power over time, equal to the product of one volt-ampere and one hour.

1. A standard unit of apparent power, equal to the product of one volt and one thousandth of an ampere (milliampere).
2. An electric measurement unit, equal to the product of one volt and one ampere, equivalent to one watt for direct current systems and a unit of apparent power for alternating current systems.
3. A unit of electric measurement equal to the product of a volt and an ampere that for direct current constitutes a measure of power equivalent to a watt.

The Système International [d'Unités] (International System [of Units]) derived unit of electric field strength; 1 volt/1 meter = 1 newton/1 coulomb.

The unit of reactive power which is equal to the reactive power in a circuit carrying a sinusoidal current when the product of the root-mean-square value of the voltage, expressed in volts, by the root-mean-square value of the current, expressed in amperes.

A test instrument that has a number of different ranges for measuring voltage, current, and resistance.
