Expert Answer:

Electric potential is that quantity which determines the direction of flow of electrons, when two charged conductors are joined by a metal wire.
 
A conductor having an excess of electrons is said to be at a negative (or lower) potential, while having a deficit of electrons is said to be at positive (or higher) potential. 
 
This difference in potential between two conductors is measured in terms of work done in transferring a unit positive charge from one conductor to the other.
It is equal to the work done in transferring a unit positive charge from one conductor to the other. 
 
Just as in nature, flow of water takes place from a higher gravitationl potential point to a lower gravitational potential point, the electric current is said to flow from a body at higher potential to a body at lower potential.
