Factors affecting conductivity

Ohm's law can be defined as the conductivity easily by the V= IR, Where V the voltage there in the sample, I the current, and R are the resistance.  Conduct determines the ability of the material to conduct the electricity.
Factors affecting conductivity
Factors affecting the conductivity measurements are mentioned as follows.
Size of the ions:
If the size of the ion increases the conductivity also increases, due to its inversely proportional to the size of the ions.
The concentration of the sample solution:
When the concentration of sample solution increases, the conductance can be decreased due to it is inversely proportional to the conductivity; therefore the conductivity measurement requires a diluted sample solution.
Nature of electrolyte:
Strong electrolytes totally dissociate into ions, consequently, the conductance of the solutions have high.
Number ions present in the sample solution:
It generally depends on the dissolution of the sample in ions. The quantity of ions in solution is specifically relative to the conductance.
Temperature:
The conductivity of the electrolyte increases when the temperature rises. This is due to ion mobility by raise the temperature.
The charge of the ions:
