Which one of the following statements concerning resistance is true?
A)The resistance of a semiconductor increases with temperature.
B)Resistance is a property of resistors,but not conductors.
C)The resistance of a metal wire changes with temperature.
D)The resistance is the same for all samples of the same material.
E)The resistance of a wire is inversely proportional to the length of the wire.

Question

Quizplus · Accepted Answer

The resistance of a metal wire changes with temperature, as the temperature increases, the resistance increases. Option A is incorrect as the resistance of a semiconductor decreases with an increase in temperature. Option B is incorrect as conductors also have resistance. Option D is incorrect as the resistance depends on factors like temperature, diameter, and length. Option E is incorrect as the resistance of a wire is directly proportional to the length of the wire.
