The internal resistance of a cell does not depend on:

CONCEPT:

• Internal resistance (r): The resistance offered by the electrolyte to the flow of ions is known as the internal resistance.
  • A cell is said to be ideal if it has zero internal resistance.

The dependency of internal resistance of a cell:

• The internal resistance of a cell is directly proportional to the distance between electrodes. 
• The internal resistance of a cell is inversely proportional to the area of the electrodes. 
• The internal resistance of a cell is directly proportional to the concentration of the electrolyte. 
• The internal resistance of a cell is inversely proportional to the temperature of the electrolyte.

EXPLANATION:​

• The internal resistance of a cell depends on the current drawn from the cell, distance between the electrode, concentration of electrolyte but independent of emf of the cell.
