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!
