    Hey guys!

    On a recent paper (January 2015) they asked a question about drawing a graph that has resistance on Y-axis and voltage on X-axis. Could someone just describe the shape of the graph.

    As long as the resistance is uniform-linear (not a semiconductor, capacitor or inductor), this will be a straight line when plotted on regularly spaced squared graph paper.

    Ohms law states I = V/R

    But the gradient of this line will be Y/X = R/V. In other words the gradient is a plot of the reciprocal of current (1/current).
