    Internal resistance

     Internal resistance-

    In case of a cell the opposition of electrolyte to the flow of current through it is the internal resistance of the cell. It is shown by r.

    1. 1. The internal resistance of a cell depends on the distance between electrodes.

      $
      r \propto d
      $

      2. The internal resistance of a cell depends on the area of electrodes

      $
      r \propto A
      $

      3. Internal resistance of a cell depends on the concentration of electrolyte

      $
      r \propto c
      $

      5. Internal resistance of a cell depends on the temperature of the electrolyte

      $
      r \propto \frac{1}{t e m p}
      $
