Question

How does an increase in the temperature affect the spcific resistance
of a:
1) Metal and
ii) Semiconductor?​

Answer 1

Hello mate...

When the temperature in increased the forbidden gap between the two bands becomes very less and the electrons move from the valence band to the conduction band. ... Thus when the temperature is increased in a semiconductor, the density of the charge carriers also increases and the resistivity decreases.

Answer 2

Answer:

here is ur answer

plz look at above pic.

hope this will helps u...be happy....
