A nonsensical statement, Sir. 100% of losses are resistive :-). Pure
inductance, whether of the self or the mutual flavour, can only store
(and retrieve) energy. If losses you want, resistance you need.

Argh! Uncle! Uncle! I give up!

You and the NatPhis are both right to take me to task on the sloppy
stuff I wrote. What I was kinda trying to get across is that the energy
transfer and energy losses are all to do with electromagnetism, rather'n
capacitive effects. And I was more or less wrong on both counts (tail
between legs) - there is an (unwanted) capacitive component to the
transfer, and as you detail the underlying mechanism for the energy loss
(inefficiency, giving rise to heating) is resistive - with actual
"ordinary" resistance dominating in small domestic transformers, while
the eddy currents (which I was thinking, loosely, about) are more
accurately considered as resistive.

We now return you to your normal broadcasts...
