I've just started a course in Electronics and I've been given a list of symbols to learn. One of them is a "+" meaning postive polarity. The other one is a "-" meaning negative polarity.
I've managed to understand, if I'm not mistaken, that all "polarity" is relative, I think. That is, if one point is more positive than another, then it can be said to have positive polarity. I think that's right anyway.
What puzzles me about these 2 symbols is:-
Where would you see them exactly? On a circuit diagram? And if yes, you'd see them on a circuit diagram, well whereabout on the circuit diagram might you see them? And what might it mean?
I do know that you get the "+" and "-" signs on the battery in a circuit. Do you actually see them in other parts of the circuit too?
I hope this question isn't too complex to answer. I've learned quite a bit about beginners electronics, but I'm probably still at about level 1.
I could just try and memorise the symbols "+" and "-" parrot fashion, but it would be nice to understand just a little of what they actually mean. Thankyou.
