Voltage Def

Voltage is a representation of the electric potential energy per unit charge.

Voltage def. In other words it is a measurement of the energy contained within an electric field or an electric circuit at a given point it is equal to the work that would have to be done per unit charge. There are multiple useful ways to define voltage including the standard definition mentioned at the start of this page. The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery. How to use voltage in a sentence.

Voltage definition is electric potential or potential difference expressed in volts. We define voltage as the amount of potential energy between two points on a circuit. Voltage definition electromotive force or potential difference expressed in volts. Voltage is what makes electric charges move.

Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light. This difference in charge between the two points is called voltage. A measure of the difference in electric potential between two points in space a material or an electric circuit expressed in volts. It is measured in volts which technically.

The greater the voltage the greater the flow of electrical current that is the quantity of charge carriers that pass a fixed point per unit of time through a conducting or semiconducting medium for a given resistance to the flow. Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. The conventional volt v 90 defined in 1987 by the 18th general conference on weights and measures and in use from 1990 is implemented using the josephson effect for exact frequency to voltage conversion combined with the caesium frequency standard for the josephson constant k j 2e h where e is the elementary charge and h is the planck constant a conventional value k j 90 0. Voltage is defined so that negatively charged objects are pulled towards higher voltages while positively charged objects are pulled towards lower voltages.

In brief voltage pressure and it is measured in volts v. There are also other useful definitions of work per charge see this section. One point has more charge than another.
