# Current of electron hydrogen atom watch

1. Calculate the current due to the motion of electron moving around the circular orbit of the radius a0 in the Hydrogen atom, where a0 = 0.59 Å is the Bohr radius

I'm not sure which equations I need to use here
I was thinking of using the coulombs law in some way but not sure if it relates to current

Maybe you could use the magnitude of the angular momentum to get a velocity?

used coulombs law to get force

then mvr=n*h/2pi and rearranged for a and got a value, but I don't know how its related to current

Current is the rate at which charges flow. Maybe get an orbital period or something to get the current out

figured it out and got the correct answer thanks for the help

So how do you do this then?
