Hello, I have a very beginner-like question.
How should I know what is the direction of current through resistors? For example, current I is here shown as current that goes from node 3 to node 4. Can I do the with the same current that goes from 4 to 3 or there is some rule that I don't know?
Sorry for disturbing with such a question, but I am a bit confused. Thanks in advance.
