What is power supply output impedance?

[ColinS]

Would it be worth starting a meta thread of electrical engineering tools like the stuff on the end of those links? Stuff like Thevenin and Norton, Ohm's Law etc.

The first three META links are filled with exactly these.

What the raw theory links (like the one's you posted) often miss is application. For a beginner, or even intermediate aspiring electronics engineer, the theory means very little with no real world examples. Just floats in the air connected to nothing. Hence threads like this one.

Perhaps I should have read the META before recommending starting a new one the same...... nevermind!

Also, those links were meant to be starting points for further reading. I wasn't trying to stifle this discussion.

The only reason the Wiki pages make sense to me is because I had a lecturer stand in front of me and my colleagues for weeks  explaining it to us. There is a balance to be struck between reading theory, being taught theory and applying those theories to real circuits.

The reading and the being taught makes the application a lot easier. I'm fortunate that I spent years being taught this stuff and being able to ask questions of experts. I guess that's whats happening here in a very much less formal setting.

I'll shut-up now.....
