Webohm: [noun] the practical meter-kilogram-second unit of electric resistance equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere. WebIt's done so because to find resistance according to Ohm's law, we are dividing the voltage by current. So when we find the slope, which is. (Δy/Δx) of the straight-line graph (i.e., resistance), we need the voltage to be on the Y-axis (numerator of the fraction) and current on the X-axis (denominator). Hence, the other way round.
