In a hydrogen atom, electron moves in an orbit of radius `5 xx 10^(-11)` m with a speed of `2.2xx10^6` m/s . Calculate the equivalent current.

Explanation

Number of rotations made by the electron/sec.
`n= V/(2pir)`
Current `i-= n.e = (2.2xx10^6)/(2pi xx 5xx10^(-11)) xx 1.6xx10^(-19)`
`=1.12 xx 10^(-3) ` amp = 1.12 mA
