Why it is not possible to determine the value of low resistance using neon flash lamp experiment?

In the neon flash lamp experiment, the resistance of the lamp is very low, often in the range of a few ohms. When measuring low resistance, the resistance of the connecting wires and contacts becomes significant and can interfere with the accuracy of the measurement. These additional resistances create uncertainties in determining the exact value of the low resistance of the lamp. Additionally, the behaviour of the neon lamp itself, which is a non-linear device, further complicated the measurement process. Therefore, it is challenging and difficult to accurately determine the precise value of low resistance using this method.
