     Best answer!

    Resistance of the material depends upon the nature of the material. 


    But there are factors that changes the value of resistance. They are listed below.


    1. length of the conductor : Resistance of the conductor is directly proportional to the length of the conductor 


    2. Temperature: For conductors, resistance is directly proportional to the square root of the temperature of the conductor.


    3. Cross- Sectional area: Resistance is inversely proportional to the cross-sectional area of the conductor.


    Hope this helps you to some extent.

    Colleen Be proud only if you earned it all on your own. Otherwise the A is not yours.
    applebottomjean1234 Since it's actually 90% my own work, then i'm proud of it, bc the other 75% of my GCSE grade will be my work, after all...

    Colleen Good, that means you actually learned what your teacher was trying to teach. The only way to learn is by doing it yourself.
