You're not getting it again, Cecil. The instantaneous current is
changing with time, but it isn't moving anywhere. e^jwt doesn't
have any space information in it.


Stick a one ohm resistor at a current loop, Jim, and then look at
the voltage across it. Surprise!!!! It's a sine wave with a positive
part, a zero crossing, a negative part, and another zero crossing.
When the voltage is +, the current is flowing through that resistor
in one direction. When the voltage is -, the current is flowing
through that resistor in the opposite direction. Sorry about that.

To maintain that there's no current flowing through a resistor when
there's an AC voltage across the resistor is ridiculous.
