The baseball analogy fills in some of the gaps that the water analogy lacks= (for me). I keep finding little tid bits in all my "study" and ran across= this in The Art of Electronics: //Quote Important: Always refer to voltage *between* two points or across two point= s in a circuit. Always refer to current *through* a device or connection i= n a circuit. To say something like "the voltage through a resistor ..." is nonsense, or = worse. However, we do frequently speak of the voltage *at a point* in a ci= rcuit. This is always understood to mean voltage between that point and "gr= ound," a common point in the circuit that everyone seems to know about. I guess that the real details come with experience. As long as I can get a= working knowledge of how capacitors, resistors, coils, diodes, transistors= , and thyristors _work together_ I think the rest will come easy. =20 //EndQuote I have also a few books I've collected over the years. At the moment I nee= d to get to the point where I can really understand them in a practical way= .. (By building something. :-) ) Forrest Mimm's "Getting Started in Electronics" and "Circuit Scrapbook Volu= me 1" Boylestad's "Electronic Devices and Circuit Theory" and "Introductory Circu= it Analysis" "The Art of Electronics" Wayne Tomasi "Electronic Communications Systems" (Don't remember where I p= icked that up, and I doubt I'll ever use it) Then "Teach Yourself Electricity and Electronics" and "Practical Electronic= s for Inventors" Lindy P.S. I worked with computers for 25 years and it wasn't until I did the Nan= d 2 Teteris did I really understand how a CPU worked. I always wanted to. = Now I've gotten around to it. So now I'm getting back around to learning = electronics.

It really, really helps to visualize electrons as though they are flowing t= hrough wires the same way water particles flow through a pipe. Increase th= e voltage/pressure and you increase the number of electrons/water particles= that flow through the pipe each second. That rate of flow for electrons i= s amperage. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
