Question

Electrical properties of solids can be measured in terms of which physical parameter(s)?

• A. Resistivity
• B. Conductivity
• C. Both $A$ and $B$
• D. None of These

Answer 1

The correct option is C Both $A$ and $B$

Conductivity is the ability of a material to conduct electricity.

Resistivity is the ability of a material to resist electricity.

$Conductivity\times \frac{1}{Resistivity}$

i.e. they are inversely proportional to each other.

Hence, both parameter can be used to measure electrical properties of solid.

Hence, the correct answer is option $\text{C}$.
