The given two quantities are almost similar and following are the differences between the two.
Electric potential |
Potential difference |
The potential at a point in an electric field is defined as the work done in moving a unit positive charge from infinity to that point. |
The potential difference between two points in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point. |
An electric potential of 1 volt at a point means that 1 joule of work is done in moving 1 coulomb of positive charge from infinity to that point. |
The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other |
