Vedclass · Answer

(C) The resistance of a material depends on its temperature. For metals like $Copper$,$Tungsten$,and $Aluminium$,the resistance increases with an increase in temperature due to increased scattering of electrons. For semiconductors like $Germanium$,the number of charge carriers (electrons and holes) increases significantly with an increase in temperature,which leads to a decrease in resistance. Therefore,the correct option is $C$.

For which of the following does the resistance decrease upon increasing the temperature?
