alright, this page is due tomorrow and i pretty lost. i figured out the first two, but im stuck on this one.
it reads:
a.) Find the equivalent resistance (4.43)
b) If I=1.0 A in the 5 ohm resistor, find the potential difference between points a and b (46.5)

i was given the answers, i just dont understand how to get there. i also dont under stand which resistors are in series and which are in parallel. any help would be great
