The following question is from my second semester physics class at UC davis.

## Homework Statement

**2. The attempt at a solution**

The reason I'm having trouble with this is because usually with circuits, we can usually tell right away if the problem is in series or parallel. This is confusing to me because I have no idea how to tell if it's in series or parallel. Does it matter which way I view it from? I tried to draw this out schematically but it still just doesn't make sense. I assumed that the middle three resistors were in series while the outer three resistors were in parallel but the answer I got doesn't match up to the answer on the answer key.

If anyone could please help me with this problem and not simply tell me what the answer is, but HOW you got the answer, it would be greatly appreciated! THANK YOU!
