Q. 8

The conductivity A. number density of free current carrier’s increases.

B. relaxation time increases.

C. both number density of carriers and relaxation time increase.

D. number density of current carriers increases, relaxation time decreases but effect of decrease in relaxation time is much less than increase in number density.

Answer :

If temperature increases, electron-hole pair will be generated more at the PN junction. If carrier increases are increased the conductivity also increase. And relaxation time will decrease when temperature increases. So conductivity depends upon the temperature.
