## Homework Equations

Series and Parallel rules

## The Attempt at a Solution

I need help just in part b. Now, when we combine the 30 and 45 resistors, the solution manual combines them in parallel and the equivillant is drawn on the bottom line. My question is WHERE DID THE WIRE IN THE MIDDLE GO? Did it miraculously dissapear?... I need tips in knowing how to determine parallel in series.. ??? Thanks for any help
