This is the simplest circuit I could think of, because I have a pretty newbie question.
The current running is 5 Amps and the voltage drop across the red dots is 5 Volts. I learned that from an Organic Chemistry Tutor youtube vid today, when trying to research my question.
What I really want to do is probe the blue dots, then the green dots. I still don't really understand how voltage works. I'm used to thinking of states as single point entities. But a potential difference is a difference between two points, so you have to pick two points to probe.
What is the voltage measured at those points?
(Btw, I made that circuit in circuit lab but the simulation didn't run, don't know why, otherwise I would try its probe tools and see what it tells me.)
I'm also aware of Kirchoff's Voltage Law, which makes me highly suspicious that the answers are +5V at the blue and -5V at the green. However, that's a "drop" of 10V, and the drop across the red dots is supposed to be 5V. So then maybe they are 2.5 and -2.5V? But that seems really odd that a 5V battery would produce 2.5V at first.
