Electric Voltage Definition

Voltage can be measured by a voltmeter.

Electric voltage definition. 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. In other words current is the rate of flow of electric charge. Voltage is what makes electric charges move. Voltage definition is electric potential or potential difference expressed in volts.

Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. These are the three basic building blocks required to manipulate and utilize electricity. In other words voltage is the energy per.

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. How to use voltage in a sentence. Voltage also called electromotive force is the potential difference in charge between two points in an electrical field. 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.

Electric potential is the energy required to move a unit electric charge to a particular place in a static electric field. Current is the rate at which electric charge flows past a point in a circuit. Voltage is measured in volts current is measured in amps and resistance is measured in ohms. Electric power like mechanical power is the rate of doing work measured in watts and represented by the letter p the term wattage is used colloquially to mean electric power in watts the electric power in watts produced by an electric current i consisting of a charge of q coulombs every t seconds passing through an electric potential difference of v is.

When beginning to explore the world of electricity and electronics it is vital to start by understanding the basics of voltage current and resistance. In the international system of units the derived unit for voltage potential difference is named volt. If a unit of electrical charge were placed in a location the voltage indicates the potential energy of it at that point. At first these concepts can be difficult to understand because we cannot see them.

In the more general case with electric and magnetic fields that vary with time the terms are no longer synonymous. Voltage is a representation of the electric potential energy per unit charge.
