To all who have contributed. This is not necessarily about EICS, (although in a round-a-bout way it is), but thought that those of you who have contributed their time and patience deserve to hear some results for your labour, (maybe of little interest but I don't care, I feel better for saying it anyway). I believe the word I am looking for is 'gratitude'.
Been reading a fair bit now and am slowly piecing things together regarding DC power. Apparently the precedent for the positive/negative thing was set 'way back when'. As 'positive' is associated with a 'surplus' and 'negative' is associated with a deficiency we sort of have two concepts of defining electricity. The 'positive' in the context we use it today would refer to 'voltage', ie; surplus of energy, and the 'negative' in the context we use it today would refer to electron flow, ie; 'current'. As it happens it seems as though I am right in one respect when I thought 'power' travelled from the '+' to the '-' but it's apparent now that this was too broad a statement to be considered valid as the 'electrons' travel in the opposite direction so one is unable to simply state or consider 'positive to negative' without further explanation. I just have to re-read this over and over now so it soaks in and becomes second nature. A reply is not necessary to this, unless of course I am still stuffing it up. My reading will continue however. If no response is noted then I can take that as a 'tick' and have passed my first 'lesson'. Neville.
