I'd be interested to see your write up, Jim. This conundrum was asked of me
in a pre-uni interview more than 40 years ago, I forget my real answer, I
think I doubted the assumption of zero resistance. There were some wacky
claims by (I think it was) Ivor Catt in a discussion on this in Wireless
World where he claimed it proved the existence of some wonderful new thingy
("displacement current"?). Much sound and fury, but little edification
ensued as I recall. I should see if I still have the letters.
My understanding is that Ivor Catt doesn't believe in displacement
current or much else of conventional electromagnetism.

It did cause me to be wary of "stated conditions" aka basic assumptions in
engineering problems in later life ;-)
A wise caution.

Ian
"Ivor Catt" sounds like I should know him... '50's, early '60's ???
Well, the wikipedia article says he was born in 1935 so that would
make him around 75.

I was talking of the year-range where I think I met him... possibly at
Motorola. With a name like that, one rarely forgets :-)
