## Homework Statement

Hi all, how do I know how the current direction are through each elements after solving a circuit (finding node voltages w.r.t GND)?

I think my understanding in electricity is rather incomplete. For example, I know that current should flow from a higher potential to a lower potential. However after solving with the node voltage method, I found out that, if you take a look at the bottom left of the image, that the current is flowing from GND to the left node (40V) through the current source. Does this not mean that the current is flowing from a lower potential now?

Assuming I've no knowledge of the mesh current method, how do I figure out the direction of current flow per circuit element?
