Question

In hydrogen atom, the electron makes $6.62\times {10}^{15}$ revolutions/sec, around the nucleus in an orbit of radius $0.5A$. Calculate the equivalent current.

Answer 1

We know that,

$I=\frac{Q}{t}=\frac{e}{t}$

But $T=\frac{1}{f}$

$I=e\times f$

$=1.69\times {10}^{-19}\times 6.6\times {10}^{15}$

So,

$I=1.05\times {10}^{-3}A$

or,

$I=1.05mA$
