In hydrogen atoms, the electron moves in an orbit of radius `5.0xx 10^(-11) m` with a speed of `2.2 xx 10^(6)ms^(-1)`. Find the equivalent curren , Electronic change `= 16 xx 10^(-19)C`

Answer

`= 1.12 mA`

Explanation

`I = (e )/(T) = (e )/(2 pi r//v) = (ev)/(2pi r)`
`= ((1.6 xx 10^(-19)) xx 2.2 xx 10^(6))/(2 xx (22//7) xx (5.0 xx 10^(-11))`
`= 1.12 xx 10^(-3)A`
`= 1.12 mA`
