• Charges kept at a distance apart create Voltage by the relation q1 q2/r multiplied by a constant. They create hills and dales of electric field.

• The legalistic definition is: the potential difference (of electromotive force) between two points of a conducting wire carrying a constant current. The common usage expands this to non-constant currents, if the magnetic field is confined (such as to the inside of a inductor).

• Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The difference in electric potential between two points (i.e., voltage) in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. In the International System of Units, the derived unit for voltage is named volt. In SI units, work per unit charge is expressed as joules per coulomb, where 1 volt = 1 joule (of work) per 1 coulomb (of charge).
