Thanks, Bruce. From what you've said, I've gathered that if the resistor is traveled in the direction of the current (ccw, 1A in this example) then the potential difference across the resistor is -IR. Thus, traveling from + to - of battery (in the direction of the current), the potential...

I have attached a redrawn circuit. Thanks. That does help. However, I am still confused on the signs for potential difference. Req=3 ohms and V=3V, thus I=1A. Also, V1 + V2 =Vbatt=3V What I'm confused about is if Va-Vb=+3V or Vb-Va=+3V or neither? and why? Thanks so much again!

Homework Statement See attached image. I'm having trouble applying the concept of potential difference in a circuit. Vb-Va=? Va-Vb=? Homework Equations Vab=Vb-Va The Attempt at a Solution The overall voltage is 5V-2V=3V. The direction of the current is defined by the higher voltage...
