A study of ohms law & resistors in series & parallel is in order.
Find an old very basic DC electronics text book. Try setting up a simple
trainer for it to learn. Hands on are BETTER than a degree. Take my word for that, I am a high school drop out that retired at 50.....
I had the same problem with SSB ( single side band), just couldnt
wrap my head around it. We had a part time audio man / EE that
had me understanding it in about 10 mn.
Analog electronics are something you get a feel for. I almost never
thought about ohms law after a while but knew by nature why a resistor
was cold or burning up !
BTW the stupid question is the one never asked !
