Question

Name the factors on which resistivity depends​

Answer 1

Step-by-step explanation:

The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. A good conductor has less resistivity. On the other hand, a bad conductor or insulator has high resistivity. The length of the wire – increasing the length increases theresistance.

Answer 2

Step-by-step explanation:

1. Length :- Resistance is directly proportional to length. That means it increases with increase in length.

2. Area :- Resistance is inversely proportional to the resistance. That means it decreases with the increase in resistance or increases with decrease in the resistance.

3. Temperature :- Resistance is directly proportional to the temperature. That is, it increases with the increase in the resistance.

4. Nature of the material :- Thick wire has less resistance and thin wire has more resistance....
