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. Informally, … What is voltage Electric field Voltage is one of the fundamental parameters associated with any electrical or electronic circuit.

Voltage is a representation of the electric potential energy per unit charge. Voltage, also called electromotive force , is a quantitative expression of the potential difference in charge between two points in an electrical field. The term recognizes Italian physicist Alessandro Volta (1745-1827), inventor of the voltaic pile—the forerunner of today's household battery.

Because voltage is defined by a ground level and some point away from ground, voltage is always and only a measurement between or across two points. There is a basic equation in electrical engineering that states how the three terms relate. This is known as Ohm's law. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. Symbol. voltage synonyms, voltage pronunciation, voltage translation, English dictionary definition of voltage. For example, in the case of a battery, the voltage is a measure of potential energy between one terminal (end) of the battery and the other. In brief, voltage = pressure, and it is measured in volts (V). It says that the current is equal to the voltage divided by the resistance or I = V/R.

Voltage is what makes electric charges move. The greater the amount of charge and the greater the physical separation, the greater the voltage or stored energy. The term recognizes Italian physicist Alessandro Volta (1745-1827), inventor of the voltaic pile—the forerunner of today's household battery. Electric Potential Difference is the true scientific term but is commonly called Voltage. Define voltage. Learn about what voltage is from this article. If a unit of electrical charge were placed in a location, the voltage indicates the potential energy of it at that point. It is the 'push' that causes charges to move in a wire or other electrical conductor. 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.. During early days of electricity, Voltage was known as Electromotive Force (emf).This is why in early formulas as Ohm’s Law, voltage is represented by the symbol E.In modern days, it is represented by the symbol “V” or “E“. In the International System of Units, the derived unit for voltage (potential difference) is named volt. Symbol. During early days of electricity, Voltage was known as Electromotive Force (emf).This is why in early formulas as Ohm’s Law, voltage is represented by the symbol E.In modern days, it is represented by the symbol “V” or “E“. The greater the amount of charge and the greater the physical separation, the greater the voltage or stored energy. Voltage is how we measure the difference in electric potential energy. How is Voltage Measured? In brief, voltage = pressure, and it is measured in volts (V). Voltage, also called electromotive force , is a quantitative expression of the potential difference in charge between two points in an electrical field. How is Voltage Measured? 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.. It can be thought of as the force that pushes the charges, but it is not a force. Voltage is seen widely in specifications of a host of electrical items from batteries to radios and light bulbs to shavers, and on top of this it is a key parameter that is … Voltage can cause charges to move, and since moving charges is a current, voltage can cause a current.

n. A measure of the difference in electric potential between two points in space, a material, or an electric circuit, expressed in volts.
