Question

An electron in a hydrogen atom makes a transition from first excited state to ground state. The equivalent current due to circulating electron:

• A. Increases 2 times
• B. Increases 4 times
• C. Increases 8 times
• D. Remains the same

Answer 1

The correct option is C Increases 8 times

Charge is the product of current and time.
Hence, $i=\frac{q}{t}$
i.e., current is inversely proportional to time, that implies current is inversely proportional to cube of $n$.
Hence, Current increases $2^3=8$ times when enters ground state from first excited state.
