investigatory project physics factors affecting internal resistance of cell class 12

My name is atul joshi of class 12th-B studying in doon international school deharadun.Sir, I want to know that how to make a project on factors affecting internal resistance of a cell and emf.I only know that internal resistance depend on nature of electrolyte.I don't know that how to make a project therefore please help me

RE: investigatory project physics factors affecting internal resistance of cell class 12
Internal Resistance of a cell:The opposition offered by the electrolyte of the cell to the flow of electric current through it is called the internal resistance of the 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

ii) Greater the conductivity 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 common area of the electrodes dipping in the electrolyte.

iv) The internal resistance of a cell depends on the nature of the electrodes.RE rI IE = V + v= IR + Ir= I (R + r) I = E / (R + r) This relation is called circuit equation. V

There are four factors that influence the resistance in a conductor.

The factors are:

(A) Conductor length
(B) Conductor cross-sectional area
C) Nature of the driver's material
(D) Temperature
