Question

Resistance of alloys decreases with the increase in temperature.

• A. True
• B. False

Answer 1

The correct option is B

False

In alloys, the increase in temperature results in an increase of its resistance, but unlike pure metals, the increase is relatively small and irregular. As the temperature increases, the molecules in the atom vibrate with more frequency, they collide with each other more frequently which makes it tough for the movement of free electrons. Thus the resistance increase with increasing temperature in the metal.
