In hydrogen atom, the electron moves in ...

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

Text Solution

Verified by Experts

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
