4. In a hydrogen atom, the electron makes ω = 6×1015 rev/s (recall that this is the angular velocity) around the nucleus. We want to calculate how much current flows through a point in the orbit. (a) Calculate the time period of the orbit. Start by converting ω into rad/s. (b) Use the definition of current to calculate I due to the revolution of the electron around the nucleus.
