On what factors does the internal resistance of a cell depend?

1.	On what factors does the internal resistance of a cell depend?
Answer» The internal resistance of a cell depends on : 1. Nature of the electrolyte : The greater the conductivity of the electrolyte, the lower is the internal resistance of the cell. 2. Separation between the electrodes : The larger the seperation between the electrodes of the cell, the higher is the internal resistance of the cell. This is because the ions have to cover a greater distance before reaching an electrode. 3. Nature of the electrodes. 4. The internal resistance is inversly proportional to the common area of the electrodes dipping in the electrolyte.

The internal resistance of a cell depends on :

1. Nature of the electrolyte : The greater the conductivity of the electrolyte, the lower is the internal resistance of the cell.

2. Separation between the electrodes : The larger the seperation between the electrodes of the cell, the higher is the internal resistance of the cell. This is because the ions have to cover a greater distance before reaching an electrode.

3. Nature of the electrodes.

4. The internal resistance is inversly proportional to the common area of the electrodes dipping in the electrolyte.
