1. The problem statement, all variables and given/known data Determine the currents in the various branches. Then there is a picture of the network which has batteries, resistors, and nodes. Most of the problems have the currents labeled. My question is when the currents are not labled how do you determine where to put them and what direction to give them? 2. Relevant equations No equations. 3. The attempt at a solution By looking at the the various electrical networks in the book it looks like you can put the currents anywhere and in any diretion.
