 TW> ????? Did You FLUNK AC theory? I though that was what Joe Said!!
Actually, I'm several weeks behind with my packet reading.  Anyway, for
power transmission lines IZ not only IR comes into play.  The only difference
between our two countries is that predominently your distribution system
AFAICR is star whereas ours is delta
And if you _really_ want to be accurate it's IZcos(theta)
If you have any more queries on AC theory then please don't hesitate to
contact me.  But not in this echo :)
 TW> that  Trunk Tracker I talked to you about the other day.  :-)
Trunk Tracker?  Wassat?  Do it run on batteries?
rgdZ :)
