1. The problem statement, all variables and given/known data See picture. 2. Relevant equations i=v/R v*(r1/(r1+r2)) 3. The attempt at a solution My question is about the solution in the picture. According to the solution, v*8/(8+16) and v*8/(4+8) equal both respective sides of the circuit A and B. My question is, why is this true? Why couldn't you take v*4/(8+16) and v*8/(4+8) for example? Why does it have to be like they wrote it? I thought the voltage divider rule was to find the voltage between two parallel resistors, but in this case it seems to be finding the voltage in two parallel resistors independently? I didn't think this was possible. Also, is the 4 and 8 on the right side parallel or in series? Does the 1 ohm resistor make them in parallel? I assume it does. Why wouldn't the solution be something like... for a) V*(8||16)/((8||16+(4||8))?
