Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
The electric potential is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field.
The amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration
Difference in electric potential between two points in space
Line integral of the electric field
The amount of electrostatic potential between two points in space. Unit: volt.
The potential energy per unit charge at a point in a static electric field.
The work (energy) required to move a reference particle from a reference location to a specified location in the presence of a force field, for example to bring a unit positive electric charge from an infinite distance to a specified point against an electric field.
The difference in potential energy between two points in an electric field; the difference in charge between two points in an electrical circuit; voltage.
The difference in electrostatic potential between two points in space, especially between live and neutral conductors or the earth.
