Question

Consider the following two statements

$\left(a\right)$ Resistance of a semiconductor decreases with increase in temperature.

$\left(b\right)$ Resistance of a conductor decreases with increase in temperature.

The correct statement(s) is/are

• A. Only $\left(a\right)$
• B. Only $\left(b\right)$
• C. Both $\left(a\right)$ and $\left(b\right)$
• D. Neither $\left(a\right)$ nor $\left(b\right)$

Answer 1

The correct option is A Only $\left(a\right)$

Resistance of a semiconductor decreases with increase in temperature while that of metal increases with increase in temperature.
