The word "volt" originates from the name of Italian physicist Alessandro Volta (1745–1827), who invented the electric battery. The term was adopted in the late 19th century to honor his contributions to the field of electricity. Unlike many scientific terms derived from Latin or Greek roots, "volt" is a modern eponym, reflecting the direct naming tradition in scientific nomenclature.
The battery provides a potential difference of 1.5 volts.
The electric car's motor operates at 400 volts.
In fencing, a quick volt can help avoid an opponent's attack.
The circuit requires at least 12 volts to function properly.
The power surge damaged devices sensitive to voltage fluctuations.
