Hello! I'm self-taught, not taking a class, and I am just starting out. I was hoping someone could give me a hand with these two questions I don't understand from the Socratic Electronics Project. Someone let me know if my picture upload doesn't work...
q1 - Is V(out) not electrically common with the ground? How do you measure the voltage drop without a loop circuit? V(total)-V(pot)? Is the added resistor there in parallel with V(out)? How do you calculate a total unknown (V(out)) in parallel with a known resistor?
q2 - In question 7, why is the ground connection in the loop on the right just after the source, pre-load? How will that circuit function? And, if it can't function, i.e. if it's shorted, how are we measuring voltage across it?
Thanks a lot!
