can u explain each factor affecting internal resistance???

 Factors affecting internal resistance are followings [R= (ρl/A)]

(i)Larger the separation between the electrodes of the cell, higher the value of internal resistance.

(ii) Lesser the resistivity of the electrolyte, lesser is the internal resistance of the cell. i.e. internal resistance depends on the nature of the electrolyte. 

(iii) The internal resistance of a cell is inversely proportional to the area of the electrodes dipping in the electrolyte.
