With increase in temperature the conductivity of

Question

With increase in temperature the conductivity of (A) metals increases and of semiconductor decreases (B) semiconductors increases and of metals decreases (C) in both metals and semiconductors increases (D) in both metal and semiconductor decreases

Tardigrade Admin · Accepted Answer

Semiconductors having negative temperature coefficient of resistivity whereas metals are having positive temperature coefficient of resistivity with increase in temperature the resistivity of metal increases whereas resistivity of semiconductor decreases.

Q. With increase in temperature the conductivity of

metals increases and of semiconductor decreases

semiconductors increases and of metals decreases

in both metals and semiconductors increases

in both metal and semiconductor decreases

Semiconductors having negative temperature coefficient of resistivity whereas metals are having positive temperature coefficient of resistivity with increase in temperature the resistivity of metal increases whereas resistivity of semiconductor decreases.
