The temperature dependence of resistance...

The temperature dependence of resistance of Cu and undoped Si in the temperature range `300 -400 K, ` is best described by :

A

Linear decrease for Cu, linear decrease for Si

B

Linear increase for Cu, linear increase for Si

C

Linear increase for Cu, expotential increase for Si

D

Linear increase for Cu, expotential decrease for Si

Text Solution

Verified by Experts

The correct Answer is:
D
Factual
Cu is conductor so with increase in temperature resistance will increase
Si is semiconductor so with increase in temperature resistance will decrease
