As far as I am concerned, there is no problem answering your questions in this thread, but, to help others in the future, it is probably a good idea to come up with a good description of each question you have and make it a thread.It does help, @Yaakov - That does help, a bit. I won't digress the point of my post, as it's kinda moved onto electronics 1-0-1 now. I'll maybe start a different thread, to try understand the "across a component". Thanks for the assistance.
