What Is Voltage Definition

If a unit of electrical charge were placed in a location the voltage indicates the potential energy of it at that point.

What is voltage definition. 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. A measure of the difference in electric potential between two points in space a material or an electric circuit expressed in volts. 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. One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

Equivalently it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. Voltage is defined so that negatively charged objects are pulled towards higher voltages while positively charged objects are pulled towards lower voltages. Voltage is what makes electric charges move. How to use voltage in a sentence.

In other words current is the rate of flow of electric charge. It can be expressed in terms of si base units. Voltage is a representation of the electric potential energy per unit charge. Voltage definition is electric potential or potential difference expressed in volts.

In other words voltage is the energy per. There are also other useful definitions of work per charge see this section. In brief voltage pressure and it is measured in volts v. Voltage definition electromotive force or potential difference expressed in volts.

The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery. It is the push that causes charges to move in a wire or other electrical conductor it can be thought of as the force that pushes the charges but it is not a force voltage can cause charges to move and since moving charges is a current voltage can cause a current. 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. Current is the rate at which electric charge flows past a point in a circuit.

There are multiple useful ways to define voltage including the standard definition mentioned at the start of this page.
