Question

On what factors does the resistance of a conductor depends on?

Answer 1

Resistance is the property of a conductor which opposes the electric current to flow through it...

Simply Resistance is an oppposition to current...and the cause of this oppostion is Collisions of charges between the atoms..

More is the Collision, Higher is the resistance...
Resistance is measured by the Ratio between Potential Difference and Current..i.e R = V/I

1-Collisions are Different for different Conductors...So as we change the conductor..i.e, we are changing the nature of conductor..for example..for copper , Silver , Gold , Collisions between the atoms are different..so Resistance will vary...

Resiatance depends on Nature of conductor..

2- If we increase the length of conductor...No. of collisions increases...as a results Resistance increases and if you decrease the lenght , collision will be lesser...so Resitance also depends on length of a conductor..

Resistance directly proportionate to the lenght of a conductor...

3- If we increase the cross sectional Area of a conductor, No. of collisions will be lesser and more for smaller area..

Thus Resistance also depends on Area of cross Section of a conductor...

Resistance is Inversely Proportional to Cross Section Area of a conductor..

4- If we increase the temperature...the kinetic energy of charge particles increases due to which No of collisions incraese..as a results Resistance increasese too...

Resistance also depends on temperature..

Hence Collision of cahrges between the atoms is the main root cause of resistnce...

So The Factors which affects the Resistance of a conductor are
1- Nature of conductor
2- Length of a conductor
3- Area of cross section of a conductor
4- Temperature...

Hope this help..

Answer 2

Factors are:-

Resistivity of the material

lenght of the conductor

cross sectional area of the conductor
