Conductivity is: A) the same as resistivity, it is just more convenient to use for good conductors B) expressed in $\Omega$^-¹ C) equal to 1/resistance D) expressed in ($\Omega$ .m)^-¹ E) not a meaningful quantity for an insulator

Question

Quizplus · Accepted Answer

Conductivity is the reciprocal of resistivity and is expressed in units of (ohm meter)^-1, which is equivalent to siemens per meter (S/m).

Conductivity Is: A) the Same as Resistivity, It Is Just Ω\OmegaΩ
