An electron of hydrogen atom is considered to be revolving round the proton in circular orbit of radius $\frac{{\mathrm{h}}^2}{\left(4{\mathrm{\pi }}^2{\mathrm{me}}^2\right)}$ with velocity $\left(\frac{2{\mathrm{\pi e}}^2}{\mathrm{h}}\right)$ The equivalent current due to
 circulating charge is

• A

  $\frac{4{\mathrm{\pi }}^2{\mathrm{m}}^2{\mathrm{e}}^4}{{\mathrm{h}}^3}$

• B

  $\frac{4{\mathrm{\pi }}^2{\mathrm{me}}^5}{{\mathrm{h}}^3}$

• C

  $\frac{4{\mathrm{\pi }}^2{\mathrm{me}}^4}{{\mathrm{h}}^3}$

• D

  none of the above
