1. The problem statement, all variables and given/known data from the diagram i drew I want to calculate the current in the battery for the circuit, can someone help me with this. Want to use symbols too. R1 and R2 are in series, they are in parallel with R3, and R4 is in series with R1, R2, and R3. The diagram is attached. 2. Relevant equations 3. The attempt at a solution Im not sure where to start with this problem, can ya get me jump started. The problem is that I realize that the diagram I have drawn has 3 resistors that are in parallel, then one that they will always be in series with. So i'm confused as to how to calculate the current when I have both parallel and series connections? I can't just use 1/r1 + 1/r2 + 1/r3/ ... etc, or series as well just series = r1+r2+r3.. etc. Please give me some help and stick with me with this today.
