The temperature dependence of resistances of and undoped in the temperature range , is best described by
(a) linear increase for , linear increase for
(b) linear increase for , exponential increase for
(c) linear increase for , exponential decrease for
(d) linear decrease for , linear decrease for
Text solutionVerified
Exp. (c)
As, we know Cu is a conductor, so increase in temperature, resistance will increase. Then, Si is semiconductor, so with increase in temperature, resistance will decrease.
