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.
