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 need to consider the contributions from both the protons and the electrons drifting across a cross-section per second.

### Step-by-Step Solution:

1. **Identify the number of protons and electrons:**
- Number of protons drifting per second, \( n_p = 1.0 \times 10^{18} \)
- Number of electrons drifting per second, \( n_e = 2.7 \times 10^{18} \)
