## Homework Statement

Given the diagram:

where R = 37 Ohms

a) Find the current in the 37 Ohm resistor

b) Find the potential difference between points A and B

## Homework Equations

DV = IR, Kirchhoff's rules

## The Attempt at a Solution

a) I = 25 V / 2 = 12.5 V (at the first (right) junction) , there for I thought I at the 37 Ohm resistor would be 12.5 V / 37 Ohms = 0.34, but it doesn't.

b) I combined the middle resistor and the lower 5 Ohm resistor to get ((1/10)+(1/5))^-1 = 3.33 Ohms and made the V at "b" 12.5 V ... but I don't know where to go from there.

Thank you so much for your time! -- I'm really stuck.
