An electron in a hydrogen atom is considered to be revolving around a proton with a velocity ` (e^2)/(n) ` in a circular orbit of radius ` (n^2)/(me^2)`. If I is the equivalent current, express it in terms of m, e, n.

Explanation

To find the equivalent current \( I \) for an electron revolving around a proton in a hydrogen atom, we can follow these steps:

### Step 1: Understand the motion of the electron
The electron is moving in a circular orbit around the proton. The velocity \( v \) of the electron is given by:

\[ v = \frac{e^2}{n} \]
