(a) Positive
(b) Zero
(c) Negative
(d) None of the above
A semiconductor has a negative temperature coefficient of resistance. If a material has a negative coefficient, it signifies that as the temperature rises, the substance’s resistance lowers. A material that has an electrical conductivity value falling between conductor and insulator is called semiconductor.
Table of content
Temperature Coefficient of Resistance in Semiconductor
- The resistance of semiconductors lowers as temperature rises because there are more electrons and/or holes available for conduction.
- Therefore, the temperature coefficients of resistance of pure semiconductor materials (such as silicon and germanium) are often negative.
A conductor has a positive temperature coefficient, meaning that as the temperature rises, so does the conductor’s resistance.
Summary:
A semiconductor has ______ temperature coefficient of resistance. (a) Positive (b) Zero (c) Negative (d) None of the above
The temperature coefficient of resistance is negative for a semiconductor. It indicates that the temperature increases with the decrease in resistance. Semiconductor materials have electrical conductivity between conductor and insulator.
