Current Electricity: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Current Electricity. Understanding the underlying formula is key to arriving at the correct answer below:

Current $I = \frac{q}{t} = \frac{ne}{t}$. Given $\frac{n}{t} = 10^{7} \text{ s}^{-1}$. Thus, $I = 10^{7} \times 1.6 \times 10^{-19} = 1.6 \times 10^{-12} \text{ A}$.
