SPEAR is a storage ring at the Stanford Linear Accelerator which has a circulating beam of electrons that are moving at nearly the speed of light (2.998 x 108 m/s). If a similar ring is about 81.0 m in diameter and has a 0.40 A beam, how many electrons are in the beam? What is the time taken by the electrons to complete one orbit? How is the amount of moving charge related to the current? electrons D -Area A Additional Materials M Reading E Show My Work (Optional) ?

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.
