resistance of a conductor...
1)is directly proportional to the length of the conductor...... i.e.more the length more the resistance...or vice versa
2) is inversely proportional to the area of cross section........ie. more the cross sectional area less the resistance....
3)is directly proportional to temperature.....more the temperature more the resistance....due to high collision between electrons... which will resist their flow....
4) it also depends on material of the wire......
that's it!!!

the resistance of a conducter depends upon
à. area of the cross section (bottom rounded part)-resistant is inversely proportional to the area of cross section.
When the area increases resistance decrease that is why thick wires are better conductor.
b . length -Resistance is directly proportional to the length of the wire.
c. nature of the material used-resistance of a conducter varies from metal to metal. for example silver has the lowest resistance and hence is the best conductor of electricity.
d . temperature -Resistance of a conducter is directly proportional to temperature. Higher the temperature more the resistance will be.
A relation between three can be written as
R proportional l/m
R=ro ×l/m
where r is the resistance ro the resistivity l is the length of the wire and a is the area of cross section.
