In an atom, electrons revolve around the nucleus in circular orbits. Can this be treated as electric current?
If an electron revolves around the nucleus 2000 times in one second, what is the equivalent current? Given charge of the electrons as `1.6 xx 10^(-19)C`.

Explanation

If the electron makes 2000 revolutions in one second, it is equivalent to movement of 2000 electrons across any point in one second.
`i=q//t="ne"//t`
`=(2000xx1.6xx10^(-19))/(1)=3.2xx10^(-16)A`.
