Define Electric Potential

Define electric potential. State its practical unit and define it.


Electric Potential: “Is the electrical state of a conductor which determines the direction of flow of charge when two conductors are either in contact or joined by a metallic wire.” 


ELECTRIC POTENTIAL “at a point is the work done in moving unit positive charge from infinity to that point in an electric field. S.I. unit is volt. 

 VOLT : “If work done in moving 1 coulomb of charge from one point to other is 1 joule, the potential difference between two points is said to be 1 volt.”
