Question

State the factors on which the resistance of a cylindrical conductor depends. How will resistance of a conductor

change if it is stretched so that its length is doubled​

Answer 1

Answer:

The resistance depends on:

(i) length of wire

(ii) area of cross section

(iii) temperature

(iv) nature of the material

As ,the resistance of a conductor is directly proportional to length of the wire. So when length of the wire is doubled ,the resistance is also doubled.

Answer 2

Answer:

For a cylindrical conductor the resistance is directly

proportional to the length of the conductor and the

resistance is inversely proportional to the area of the

conductor that is resistance is inversely proportional to

the square of the radius of the cylindrical conductor.

If it is stretched so that its length is doubled without c

hanging its volume
