Question
Physics Question on Semiconductor electronics: materials, devices and simple circuits
A pure semiconductor has a/an
A
finite resistance which decreases with temperature
B
infinite resistance at 0∘ C
C
finite resistance which increases with temperature
D
finite resistance which does not depend upon temperature
Answer
finite resistance which decreases with temperature
Explanation
Solution
Since a semiconductor has a negative temperature coefficient of resistance, its resistance decreases with temperature.
