Question

What is a potential difference of a cell ?

Answer 1

1. The potential difference is the amount of work done in moving a unit charge.
2. The unit of potential difference is Volt.
   $1\mathrm{volt}=\frac{1\mathrm{joule}}{1\mathrm{coulomb}}$
3. Cell potential is a measure of the potential difference between two half cells in an electrochemical cell.
4. The potential difference is caused by the ability of electrons to flow from one-half cell to another.
5. The anatomy of an electrochemical cell is given above in the image.
