Q. As the temperature rises the resistance offered by metal
A) Increase
B) Decrease
C) Remains same
D) None of these
Explanation
(a) Near room temperature, the electric resistance of a typical metal conductor increases linearly with temperature.
$R = R_{0}(1 + \alpha T)$
Where $\alpha$ is the thermal resistance coefficient.
