Voltage - Wikipedia
WebVoltage, 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.

How Voltage Works - Circuit Basics
WebJul 22, 2021 · Voltage is the force that makes charges flow. Voltage is also known as the electromotive force or EMF. It is the potential difference between two terminals where one terminal has more electrons gathered compared to the other terminal. Voltage is measured in Volts (V), which is the derived unit for electric potential.
Voltage | Definition, Calculation & Typical Values - Magnetism
WebVoltage, denoted by V, is defined as the amount of work energy needed to move a unit of electric charge from a reference point (a) to a specific point (b) in an electric field. ΔV = Va – Vb. In the International System of Units (SI), the electric potential is expressed in units of joules per coulomb (J⋅C −1 ), or volts (V).
What Is Voltage? (Definition, Units of Measurement and FAQs)
WebApr 20, 2022 · Voltage is defined as the pressure that is present to push electricity around a circuit or system. Voltage is quantified by the unit volt (V). The higher voltage the more electricity that can flow around a circuit or device, the lower voltage means that less electricity can flow around a circuit or electrical device.
