Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. [1] [2] In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point.
May 9, 2024 · Voltage (also known as electric potential difference, electromotive force emf, electric pressure, or electric tension) is defined as the electric potential difference per unit charge between two points in an electric field. Voltage is expressed mathematically (i.e. in formulas) using the symbol “V” or “E”.

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. In brief, voltage = pressure, and it is measured in volts (V).
Nov 2, 2022 · Learn what voltage is, how to calculate it, and how to measure it in electric circuits. Find out the difference between direct voltage and alternating voltage, and the sources and symbols of voltage.
Learn the basics of electricity and electronics with this tutorial on voltage, current, resistance, and Ohm's Law. Use a water tank analogy to understand how these concepts relate to each other and how to measure them.
Voltage is the pressure of the power source that exerts on an electrical circuit. And, the pressure pushes the charge electrons through a conducting loop. The movement of electrons sets up current in the electrical circuit. As a result, the work is done by the current in the presence of voltage.
