Ohm's Law

[J Howland]

Can you increase voltage and current simultaneously?

I use to with my free energy machine, but the aliens took it.:wink:

I think the relativistic approach should be heard. If the current and voltage are both thought of as observers of an event; i.e., the voltage starts to rise and then "sees" the electron start to respond; the current rises, and then "sees" the voltage rise.

There is no cause and effect here...both effects happen simultaneously. It is only with relativistic effects that either event appears to have happened "first." Newtonian physics and mathematics, and the calculus based upon them do not work perfectly for anything involving electrons.

Kind of the point of the 2nd part of #120. Two events can't really be simultaneous unless they occupy the same space. Like I said, probably a little too silly for what we are talking about.

For practical purposes, the change can occur simultaneously and does not require any magic, aliens not withstanding.
