Electrical conductivity of a semiconductor |
|
|
a) |
Increases with the rise in its temperature |
|
b) |
Decrease with the rise in its temperature |
|
c) |
Decrease does not change with the rise in its temperature |
|
d) |
First increase and then decreases with the rise in its temperature |

(a) Electrical conductivity of a semiconductor increases with rise in temperature because more covalent bonds will be broken with rise in temperature. Due to which more number of electrons and holes will be available for the conduction of electricity in a semiconductor. |
