What's the charge density of an electron?
Pete, you know I don’t have the maths to do justice to this, but if asked a question, I like to do my best to respond.
Besides, some day I may want to take you to task for not answering.
My understanding is that the charge density of a particle is the ratio of its charge to its volume.
I assume, from the context; also from a post of yours in Physics Forums that I struggled with a few years ago; that you are saying that the charge density of an electron is infinite (?)
My thoughts would be along the lines that the charge is finite and the volume is finite, so although the ratio may be mathematically “infinite”, two finite entities do not equal a physical infinity.
