In a discharge tube the number of hydrogen ions (i.e., protons) drifting across a cross- section per second is `1.0xx10^(18)`, while number of electrons drifting in opposite direction across another cross-section is `2.5xx10^(18)` per second. If the supply voltage is 220 V, what is the effective resistance of the tube ?

Explanation

To find the effective resistance of the discharge tube, we will follow these steps:

### Step 1: Calculate the total current (I)
The total current is the sum of the currents due to the hydrogen ions (protons) and the electrons. The current contributed by each type of charge carrier can be calculated using the formula:

\[ I = N \cdot e \]

where:
