Question

With the rise in temperature, the resistance of semiconductor

• A. increases
• B. decreases
• C. sometimes increases and sometimes decreases
• D. remains unchanged

Hint:

Unlike metals, the resistance of semiconductors decreases with increasing temperature due to the increased movement of charge carriers.

Answer 1

The Correct Option is B

Step 1: Understanding semiconductor behavior.
In a semiconductor, the resistance decreases as the temperature increases. This is because, with increased temperature, more charge carriers (electrons or holes) are released, which increases the electrical conductivity of the material. Therefore, the resistance of a semiconductor decreases with rising temperature.
Step 2: Conclusion. The correct answer is that the resistance of a semiconductor decreases with rising temperature.
