Assertion: If the temperature of a semiconductor is increased then its resistance decreases.
Reason: The energy gap between conduction band and valence band is very small

Statement-1 : When the temperature of a semiconductor is increased, then its resistance decreases. Statement-2 : The energy gap between conduction band and valence band is very small for semiconductor.

Assertion (A): As the temperature of a semiconductor increases, its resistance decreases. Reason (R ): The energy gap between conduction band and valence band is small.

The energy gap between conduction band and valence band is order of 0.07 eV. It is a

in a good conductor the energy gap between the conduction band and the valence band is

In a good conductor the energy gap between the conduction band and the valence band is

There is a small energy gap between the conduction and valence bands of
