**noun**)

2. A locked room where money or valuable things are kept: "I had never been in the bank vault before."

2. A quick jump or movement during fencing to avoid a thrust: "The fencing master taught the students how to use the volt so their opponents couldn't score."

When the man was exploring the ancient **vault** under the market square, he carried a nine **volt** battery for his portable light so he could see if he needed to **vault** over the broken stones.

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.

*absolute volt*involve mechanical effects and are inherently difficult, usually requiring many years to complete.

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.

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

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.
