    Resistance of a non-ohmic device from its I/V graph

    Thank you for the help. I think the answering scheme was dodgy, the resistance should be very small.

    Resistance of a non-ohmic device from its I/V graph

    What is the resistance of Device Q when a current of 200mA flows through it? Wouldn't the resistance of the device be approaching 0 Ω as its characteristic resembles one of a diode (gradient = 1/R)? Apparently, the answer is just using V = I R, and solving for the resistance. Is there...
