A volt is electrical potential which represents electic field strength.The electric field is the spacial derivative of the potential. Take the case of an electric field between two parallel flat plates spaced "d" apart. If the potential difference between the plates is V, the electric field between them is V/d. This field will accelerate a charge and impart energy to it. The meaure of the energy gained is the potential difference times the charge.. Electron volt is a unit of energy, and is equal to the energy imparted to a charge equal to the charge of an electron subject to a potential difference of one volt.

A volt is a measure of electric potentital, that is, how hard the electriclty is pushing. An electron volt (abbreviated eV) is a measure of energy, defined as the amount of energy contained in a charge of 1 electron at a potential of one volt. The charge on an electron is about 1.6 x 10^-19 coulombs (or 6 x 10^18 electrons per coulomb). An electric current flow of 1 coulomb per second is 1 ampere.
For example, if you have a 9 volt battery putting out a current of 0.1 amps then each electron has an available energy 9 eV. The electron energy in eV is the same as the battery voltage in volts. The 0.1 amps is how mant electons per second are flowing, for 0.1 amps that is 6 x 10^17 electrons per second.
In SI units, 1 eV is 1.6 x 10^-19 Joule and one Volt is 1 Joule/Coulomb

The means required to flow one electron in the course of two factors with an electric technique of a million Volt is a million eV. Volt is a level of electric means, like how eagerly the electrons want to flow from one place to a diverse in the course of two factors. eV is a level of means. Refer back to the 1st paragraph.

Basically none, voltage if made up of an excess ( + ) or deficiency of ( - ) electrons.
