Care to explain the difference? I think this conversation is awfully
close to bordering on semantics. So I suppose a definition of
electrical current and ionic current is in order. I think we all agree
that ionic current can simply be characterized as the net flow of charge
due to translational motion of ions. So is "electrical current" that
current due to electron flow only, or can it be characterized simply by
net flow of charge?
