Howdy, gang!
So, I've got me a few questions regarding Ohm's Law. I know - what could be simpler, right? Well, actually it's more about how one value affects the others.
I mean, I understand that E = I*R, I = E/R & R = E/I; easy kid stuff, really. What I DON'T get is - when you change one quantity, which other quantity ( quantities ) change & why?
For example: let's say we have a circuit with 1 amp at 1 volt & 1 ohm resistance. Beautiful!- Ohm's law is happy & we're all good. But now, suppose we swap out our 1 ohm resistance for 2 ohms. Now, it seems to me there are 3 possibilities: A. Voltage changes ( doubled ) B. Current changes ( halved ), or C. BOTH values change to some degree.
O.K.- so, here's my primary question: when we change one value ( either E,I, or R), which other value(s) change and, more importantly, WHY?
Next question: can we predict and/or CONTROL which value(s) change? And, if so, HOW?
You see, I've read plenty of electronics text forwards & backwards, but none of them really seem to address this question, which has been bugging me for years! Can anybody share some insight on this matter? Any information at all would be most appreciated! Thanks in advance, folks & s'long for now!
Hasta, La Vista, Baby!
