WebResistance is measured in units called ohms (Ω). The amount of current flowing in a circuit is affected by the resistance of that circuit. Each component in a circuit has a resistance.... 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. ( 5 votes) Kinjal
