electron is in a circular orbit of radius r = 41011 m, and its speed is v = 2.51625106 m/s. 1. Find the "current" of the electron's orbit. Hint: current is defined as the charge per unit time passing a point. The electron has charge e = 1.602 1019 C and time it takes to pass the same point once each orbit can be found because time is distance divided by speed
