Thanks to all who have provided me with meaningful answers that I can
ponder and look up further, to get more knowledge in the subject.

I have recently purchased what I feel is an excellent book, written
'at my level'. The book is: "Basic Electricity" by Van Valkenburgh,
Nooger & Neville, Inc.

I may come across something in the book I don't understand, and
therefore post my question(s) here.

I'm actually overwhelmed at the number of responses, and insightful
info, my thread generated.

Thanks,
George
