Correct option is B
Conductivity and resistivity are inversely related properties of a material. Conductivity (σ) measures how easily electric current can flow through a material, while resistivity (ρ) measures how much a material resists the flow of electric current.
The relationship between conductivity and resistivity is given by:
σ = 1/ρ
For a material with low conductivity, the resistivity must be high because they are inversely proportional.
Explanation of the Options:
High conducting material (a): This option is incorrect because it implies high conductivity, which is the opposite of low conductivity.
High resistivity (b): This is the correct option. Low conductivity means that the material does not conduct electric current easily, which corresponds to having high resistivity.
Low resistance (c): This option is incorrect. Low resistance implies high conductivity, which is not the case for a low-conductivity material.
Low resistivity (d): This option is incorrect. Low resistivity implies high conductivity, which is the opposite of low conductivity.
Therefore, the correct answer is:
(b) High resistivity
