Question

How does the resistance of:

i) a semiconductor, and

ii) an alloy

vary with temperature?

• A. i) Inversely proportional, ii) Directly proportional
• B. i) Directly proportional, ii) Unaffected
• C. i) Increases with increase in temperature, ii) Inversely proportiona
• D. i) Decreases with increase in temperature, ii) Unaffected

Answer 1

The correct option is D

i) Decreases with increase in temperature, ii) Unaffected

i) The resistance decreases with increase in temperature.

ii) The resistance of an alloy remains nearly unaffected by change in temperature.
