In Bohr's model of the hydrogen atom, the electron moves in a circular orbit around the proton. The electron passes by a particular point on the loop in a certain time, so we can calculate a current (I = Q/t). An electron that orbits a proton in a hydrogen atom is therefore analogous to current flowing through a circular wire (Figure ...
