The question is based on a completely erroneous assumption. Electrons per second per square meter is a current density, if an electron's charge is accounted for. In electronics, it is usually current, not current density, that matters. The OP typically asks abstruse questions that, on analysis, are only approximately meaningful. I can imagine that he was praised as a child for asking what the adults around him thought were deep questions, and that he has essentially retarded himself deliberately in an attempt to relive the days of easy praise. There's a line in Gilbert and Sullivan's /Patience/: "If this young man expresses himself in terms too deep for me, Why, what a very singularly deep young man this deep young man must be!" Poor young man! Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������
