What is potential difference of a cell?

Cell Potential is the measure of the potential difference between two half cells in an electrochemical cell.

  • The potential difference in a cell is caused by the ability of electrons to flow from one-half of the cell to the other.
  • Electrochemical cell anatomy is given below –
