the direction of current (1 Viewer)

[Jocharles]

It seems to me that in some questions you assume that current flows 'conventionally' (electrons flow positive terminal to negative terminal ). However it seems sometimes you are suppose to assume its natural flow (electrons flow from negative to positive). How do i distinguish which one to use so i can apply myself to the question?

It'll either say current or electron flow

Most questions will have an arrow and the letter "I" above it. This represents the conventional current which is always + to - direction flow or + charge movement.

Any other form will explicitly state in the question "electron flow" which is obviously the opposite direction. This style of question is covered in the Ideas-to-implementation topic and F=QVBSintheta questions.
