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

Q. 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 4 times

(b) decreases 4 times

(c)increases 8 times

(d) decreases 8 times

Ans: (c)

Sol: Equivalent Current , I = e/T  and T ∝ n³/Z²

When electron makes a transition from n=2 to n=1

current increases by 8 times (As n³ = 2³ = 8)
