A) The resistance of \[Al\] will increase and that of \[Si\] will decrease
B) The resistance of \[Al\] will decrease and that of \[Si\] will increase
C) Resistance of both decrease
D) Resistnance of both increase
Correct Answer: B
Solution :
\[T\downarrow \] (\[300K\] to \[70K\]) \[T\downarrow \underset{(Al)}{\mathop{{{R}_{metal}}}}\,\downarrow \underset{(Si)}{\mathop{R}}\,\uparrow \]semi - conductorYou need to login to perform this action.
