The electrical resistivity of a semiconductor

Question

The electrical resistivity of a semiconductor (A) increases with temperature (B) decreases with temperature (C) increases at low temperature and then decreases (D) does not change with temperature

Tardigrade Admin · Accepted Answer

Resistivity of semiconductors decreases with increase in temperature because at higher temperature, the number of current carriers increases.

Q. The electrical resistivity of a semiconductor

increases with temperature

decreases with temperature

increases at low temperature and then decreases

does not change with temperature

Resistivity of semiconductors decreases with increase in temperature because at higher temperature, the number of current carriers increases.
