Rob,
I believe 'time varying fields' is not the only condition. To bring
displacement current into play, the other condition is the geometry of
structure(incl. material).
Let us consider two mundane examples: 1) ordinary light bulb, and 2)
florescent(tube light) bulb - both excited by time varying fields. How
would you explain displacement current in each case?
Thanks,
Sainath
