In the case of hydrogen atom, an electron moves in an orbit of radius 5x10-11 m with a speed of 2.2 x 106 ms-1. Calculate the equivalent current. Given: charge on an electron = 1.6 x 10-19C.
Radius of the orbit, r = 5 x 10-11m
Speed of electron,
Number of revolutions in 1 second,
Charge flowing in one second, q = nr
