Hello all. I don't know how long I'll be on this forum.. I guess it depends on the answers I get here.. well anyway, here are two questions:
1. I have studied electronics for quite some time, and have read through different books and tutorials. Some use the conventional method saying that positive goes to negative. Others use the "newer" method where negative goes to positive. Then some guys start confusing is saying that there are "holes" and "charge carriers" that either hold an electron, or a hole.. And then there are guys that say stuff comes from the negative AND the positive. Well, I basically understand the reasoning of all of them (except the last one)... my main question is this: Are all of these just theories has there actually been something proven? If all are just theories, the authors seem to be using them as facts. If something has been proven, then the other authors are incorrectly teaching just because they can visualize/explain it better?
2. Unless using a transistor, in my experience, I have found that voltage and resistance rules the circuit. You then use ohms law to figure out the current. However, the world is not perfect and a power source cannot produce an unlimited amount of current (presently). So, I am guessing that when too much current is asked for, the ohms law work in reverse, and you have to find out the voltage. Either that or you start breaking ohms law.. But anyway, what happens when, with a limited current, you have a parallel circuit? In theory, ohms law works out that all the current is divided out, depending on the voltage. If there is not enough current, something strange happens..? I tried looking it up in different tutorials and everything... I didn't find it anywhere. Anybody know what happens?
Well, yeah.. I would be greatfull if anybody could answer my questions. I was wondering about them for quite some time.
