On what factors does the resistance of a conductor depend?
The electrical resistance of a conductor depends on the factors listed below:
1) Nature of the material of the conductor – eg. A wire made of copper would be a better conductor than a wire made of iron
2) Length of the conductor – eg. A shorter wire would be a better conductor than a longer wire
3) Area of cross-section of the conductor – eg. A thick copper wire is a better conductor than a thin copper wire
4) Temperature of the conductor – resistance goes up with increase in temperature
