Using Bohr model, calculate the electric current created by the electron when the H-atom is in the ground state.


consider the hydrogen atom

Let the electron be in ground state,


Now the current by definition is the amount of charge passing through a cross sectional area in a unit time.


Now the time period for the electron’s rotation,


,


where v = orbital velocity of electron


T=time period of the electron


r= radius of the 1st orbit.


Now by definition we know current,


Substituting value of T in above equation, we get,



the current produced by revolving electron of hydrogen atom
