Question

What will be effect on the resistivity of a conductor, if the length of the conductor is made four times?​

Answer 1

Explanation:

even the resistivity increases by 4 times...because resistivity depends on nature of material..

Answer 2

Answer:

the resistance of a conductor is directly proportional to its length. so if length is increased then resistivity increases ande vice versa. so if length is doubled resistance will also get doubled i.e resistance is 4 times that of original resistance. after this see the image......
