The ** electric potential and voltage ** is the physical measure, which defines the potential difference between two points, proportional to the energy required for moving from one point to another of an electrical charge.

The ** electric potential and voltage ** is the physical measure, equal to the ratio of potential energy, which is possessed by the positive charge, positioned in that point of the field to this field.

** 1 volt** is the electric voltage that in an electrical circuit causes a current of 1 ampere at power of 1 watt.

** 1 volt** is the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt.

** 1 volt** is the electric potential, in which the charge of 1 coulomb possesses potential energy of 1 joule.
