Question

On which factors does the resistance of a conductor depend write an expression relating all the factors

Answer 1

The resistance of a conductor depends:

•it is directly proportional to the length of the conductor.i. e R directly proportional to L .

•it is inversely proportional to cross sectional area.i.e R inversely proportional to A

•depends upon the nature of the conductor.

•increases with increasing temperature.i. e R directly proportional to T
