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 : increases 8 times

Solution :
$$\eqalign{ & i = \frac{q}{T} \cr & {\text{Now,}}\,\,{T^2} \propto {r^3} \propto {n^6} \cr & \Rightarrow i \propto \frac{1}{{{n^3}}} \cr} $$
