Homework Help: Axis question for electricity experiment question.

  1. Jan 12, 2012 #1
    In an experiment to demonstarte relationship between current and p.d. in an electrilyte the book says to plot current on the Y axis. Why is this?

    V = IR
    R = V/I

    I always assumed when you plot graphs, the slope must equal the constant.

    Any input appreciated.

    It's not an unbreakable rule, merely a convenience and convention. If it bothers you, consider that Conductance (G, in Siemens) is the reciprocal of Resistance (R, in Ohms). Thus I = V*G.
