B) resistance
C) resistivity

Question

Quizplus · Accepted Answer

The ratio of voltage to current in a material or device represents its resistance, which is a measure of how much it opposes the flow of electric current. This is true regardless of whether the material or device obeys Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. Resistance is a fundamental electrical property, distinct from conductance (which is the reciprocal of resistance) and resistivity (which is a material property reflecting how strongly a material opposes current flow).
