Homework Equations
No actual equations are necessary, our teacher just told us that:
1. In a pathway, Voltage in = Voltage out
2. The current that enters a junction must leave that junction.
The Attempt at a Solution
We've been assigned pages and pages of these, and these 4 are the ones I had trouble with. In the first diagram, v2= 90-70=20v. I'm stuck from there.
I normally look for online tutorials myself, but I couldn't find any of these ones- without resistance.
Thanks, all help is appreciated.
