[amp_mcq option1=”R = s2″ option2=”R = s” option3=”R > s” option4=”R = 1/s” correct=”option4″]
The correct answer is: D. R = 1/s
Resistivity is the measure of how difficult it is for an electric current to flow through a material. Conductivity is the measure of how easily an electric current can flow through a material. The relationship between resistivity and conductivity is given by the equation:
$R = \frac{1}{s}$
where $R$ is the resistivity, $s$ is the conductivity, and $\Omega$ is the ohm.
Option A is incorrect because resistivity and conductivity are inversely proportional to each other. Option B is incorrect because resistivity is not equal to conductivity. Option C is incorrect because resistivity is not greater than conductivity.
