1. The problem statement, all variables and given/known data What is the current and potential difference across the 4Ω, 12Ω, and 8Ω resistors. What is the potential difference across a and b https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/389632_3598331272733_1107039398_3285590_155442550_n.jpg [Broken] 2. Relevant equations V=IR ΔV=ε-IR 3. The attempt at a solution What we are having difficulty finding out is the potential difference across the resistors. What we are unsure of is whether the potential difference the change in Voltage as it goes through the resistor or the Voltage after it goes through the resistor. Our teacher gave us rather original way to solve this, so please don't knock it...too much. we found I in the top loop is 1 amp and I in the bottom is 1.5 amps. We have also determined the potential difference from a to b (which isn't written on the image, but is from the junction on the right to the junction on the right). It seems really obvious, but we are just not sure which figure we are supposed to use to determine it and the solution in the book is just confusing us. Thanks!
