Accelerating electrons? Don’t they move at the speed of light? What the heck?!
My bad - electrons don’t go the speed of light - my mistake, sorry everybody!
They (electrons) move at a high fraction of the speed of light. But, since they have mass they can never achieve the full speed of light.
Nope, not at the speed of light in a vacuum, anyway. Even silver, best conductor in nature, slows them down a bit.
