A device obeying Ohm's law must have a resistance which
A) is zero.
B) is proportional to current.
C) is constant.
D) is proportional to voltage.

Question

Quizplus · Accepted Answer

A device obeying Ohm's Law has a constant resistance, as Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, implying that resistance (R = V/I) remains constant.
