direction of current flow

From the article

" In this method, we assume directions of currents in a network, then write equations describing their relationships to each other through Kirchhoff's and Ohm's Laws."

It means you can pick the current directions any way you want. Solving the resulting equations will just give you a negative current if the direction you picked is opposite of the actual current.

Welcome to AAC! This should have been asked in the electronics chat area, for the reason above.

To answer your question, look at the second sticky note on top of the Feedback and Suggestions forum, Conventional flow vs Electron Flow.
