In a discharge tube, the number of hydrogen ions (i.e., protons) drifting across a cross-section per second is `1.0xx10^(18)`, while the number of electrons drifting in the opposite direction across another cross-section is `2.7xx10^(18)` per second. If the supply voltage is 230 V, what is the effective resistance of the tube ?
