By increasing the temperature, the specific resistance of a conductor and a semiconductor

A

Increases for both

B

Decreases for both

C

Increases, decreases

D

Decreases, increases

Text Solution

Verified by Experts

The correct Answer is:
C
For conductor
`T uarr tau darr rho uarr`
For semiconductor
`T uarr` Covalent bond gets break and more no. of free electrons are obtained hence `rho darr`
