When the temperature of a conductor increases the ration of conductivity and resistivity ………….

A

remain constant

B

increase

C

decrease

D

increase or decrease

Text Solution

Verified by Experts

The correct Answer is:
C
When temp of conductor increase its conductivity decrease and resistivity increase.
`rho= (1)/(sigma)`
Conductivity is reciprocal of resistivity
`(sigma)/(rho)= sigma^(2)`
So it decrease.
