factors affecting the internal resistance of a cell
Factors affecting Internal Resistance of a cell: i) Larger the separation between the electrodes of the cell, more the length of the electrolyte through which current has to flow and consequently a higher value of internal resistance. ... i.e. internal resistance depends on the nature of the electrolyte.
* The internal resistance of a cell is inversely proportional to the common area of the electrodes dipping in the electrolyte.
- LENGTH OF THE CELL.
-CROSS SECTION AREA OF THE CELL.
-PROPERTY AND NATURE OF THE CELL.
-TEMPERATURE OF THE CELL.

internal resistance depends on the nature of the electrolyte. iii) The internal resistance of a cell is inversely proportional to the common area of the electrodes dipping in the electrolyte. iv) The internal resistance of a cell depends on the nature of the electrodes.
Internal resistance is the amount of resistance offered to the electrolyte of a cell to the flow of current between its electrodes.The internal resistance of cell depends on the following factors :-Nature of electrolyte. Concentration of the electrolyte. Distance between the electrolytes. With the increase in common area of the electrodes, the internal resistance decrease. Temperature is inversely proportional to internal resistance.

macro environment. 1. The major external and uncontrollable factors that influence an organization's decision making, and affect its performance and strategies. These factors include the economic factors; demographics; legal, political, and social conditions; technological changes; and natural forces.
The internal resistance of a cell is affected by following factors
1.Area of electrodes
2.Seperation b/w the electrodes
3.Concentration of the electrolyte
4.Nature of material of electrode and electrolyte
➡ Larger the distance b/w the electrodes of the cell then higher the value of internal resistance.
.➡ Greater the conductivity of the electrolyte lesser is the internal resistance of the cell
➡ The internal resistance of cell is inversely proportional to the common area of electrodes dipping in the electrolyte.
Here is your answer :-
• INTERNAL RESISTANCE OF A CELL
When a current drawn from a cell , in the external circuit it flows from anode to cathode and inside the cell through electrolyte , it flows from cathode to anode to maintain continuity . The electrolyte offers certain resistance to flow of current . This is called as internal resistance of a cell .
• FACTORS AFFECTING INTERNAL RESISTANCE
#Distance between two electrodes . : - Directly proportional.
#Area of cross section of the electrodes :- inversely proportional.
#Depends upon the nature , concentration and temperature of the electrolytes.
