What Is Voltage A Measure Of

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit expressed in volts it measures the potential energy of an electric field to cause an electric current in an electrical conductor.

What is voltage a measure of. In brief voltage pressure and it is measured in volts v. In this analogy charge is represented by the water amount voltage is represented by the water pressure and current is represented by the water flow. How to measure voltage. 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.

Determination of the difference in electrostatic potential between two points. Voltage is represented in equations and schematics by the letter v. The unit of voltage in the international system of units si is the volt defined as the potential difference between two points of a conducting wire carrying a constant current of 1 ampere when the power dissipated between these two points is equal to 1 watt. There are several ways in which voltage measurements can be made but one of the most common is to use a multimeter.

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. The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery. In the international system of units the derived unit for voltage potential difference is named volt.
