Physics Question on Current electricity
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
Answer
semiconductors increases and of metals decreases
Explanation
Solution
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.
