Superposition of voltages and currents seems to be quite

line analysis.

Do you really expect us to believe that those voltages
and currents can exist without energy? Maybe an example
of EM voltage and EM current existing without ExB joules/sec
would help.

and yet again you cross up terms... voltage and current are on wires. E
and B are fields between or outside of wires. while they can be handled
similarly they should not be compared directly as you are asking. and
yes, there is at least one very good example of a voltage without ExB...
just charge a balloon up with some stray electrons and leave it alone long
enough to reach steady state... voila, E with no B. Please do this
experiment and reply when you have truly reached steady state.
I've been waiting for someone to open the door so that Art could take
part in this thread.Dave, your use of the balloon as an example will do the
job nicely. Art will now be able to contribute quite a lot, although I'm not
sure that he ever reaches steady state!
