In a hydrogen discharge tube, the number of protons drifitin across a cross section per second is `1.0xx10^(18)`, while the number of electrons drifting in the opposite direction across the same cross section is `2.7xx 10^(18)` per second. Find the curernt flowing in the tube.

Explanation

To find the current flowing in the hydrogen discharge tube, we can follow these steps:

### Step 1: Identify the charges and their respective drift rates
- The number of protons drifting across a cross-section per second:
\[ n_p = 1.0 \times 10^{18} \text{ protons/second} \]
- The number of electrons drifting in the opposite direction across the same cross-section per second:
