Volt (Volt) (the sign is V) measure the voltage, or difference of electrical potential in the international system of units.

The Volt is also a unit of measure difference of electrical potential or voltage is the difference of electric potential relative to the potential reference or ground electrical which has a voltage fixed to zero. expression.

volt electromotive force as well. a Volt is the amount of energy produced by a electrical source is to displace a Coulomb load applied and the work is equivalent to a joule do. Called the Volt in honor of physicist and inventor, Volta (1745-1827) to the YK, and the cases applied, it is dedicated.
