if you use loop current, then please name the loop currents
L_1, L_2, ... and continue to find the branch
current, as done in the second paragraph on page 97.
In class we learned how to find the branch current directly.
Use the method we used in class; you will need to introduce a current
for each branch so in problem 5 you have 9 currents I_1, I_2, ..., I_9).
