Voltage, also known as potential difference, electric pressure, or electric tension, is the difference in electric potential between two points. In a static electric field, it corresponds to the work
Batteries are sources of voltage in many electric circuits.

The volt, named after Alessandro Volta, is the unit of measurement of electric potential, electric potential difference, and electromotive force in the International System of Units.

…move a positive test charge from the first point to the second point. In the International System of Units (SI), the derived unit for voltage is the volt (V). The voltage between points can be caused by the build-up of electric charge (e.g., a capacitor), and from an electromotive force (e.g., electromagnetic…
