As in, circuits with multiple batteries. Can someone explain why the loop and current directions when using kirkhoffe's rules are arbitrary?
Because if you choose the direction to be wrong, you'll simply end up with a negative current. However, you should avoid kirchhoff's rules in circuit analysis as they result in horrendous systems of equations to solve, so instead learn the node voltage and mesh current analysis method, they reduce the number of equations and make your life easier. They are simply more simplified versions of kirchhoff's laws intended for analysis.
If your only issue is multiple batteries, I think its easier to do superposition with the batteries. But really just do whatever you're most comfortable with.
