Potential difference of a cell
The difference in potential between the positive and negative terminals of a cell is the potential difference of that cell. This potential difference is caused by chemical reactions occurring inside the cell. The potential difference sets the electrons in motion and results in the flow of electricity through a conducting wire connected to the two ends of the cell.
The amount of work done to carry a unit positive charge from point A to point B is called the electric potential difference between the two points.
Potential difference between two points= Work/ Total charge transferred.
The unit of potential difference in SI system is volt. V= W/Q.
1V= 1J/ 1C
