Question

Which of the following is wrong? Resistivity of a conductor is
(a) independent of temperature.
(b) inversely proportional to temperature.
(c) independent of dimensions of conductor.
(d) less than resistivity of a semiconductor.

Answer 2

The wrong statement regarding resistivity is option (B)

Explanation:

• Resistivity of a conductor is a property tells us capacity of electric current pass through the given material .

• And the material through which large amount of electric current is passed called conductors and they have low resistivity than semi conductors thus, option (d) is correct here.

Resistivity is independent of temperature and dimension of a material thus option (b) gives us the wrong idea about resistivity and so it is the one wrong statement.
