Quizplus · Accepted Answer

For an ohmic material, the slope of the graph represents resistance. This can be seen from Ohm's Law, which states that the current through a conductor is directly proportional to the voltage applied to it, and the constant of proportionality is the resistance of the conductor. Therefore, the slope of the graph is equal to the resistance (ΔV/ΔI).
