I attached a picture of the problem. I am confused about how the current source will affect the direction of current flow. Does the current flow in the direction of the current source arrow? If not what does the arrow dictate? Our professor said the direction of the current flow does not matter but when I tried solving this using the loop method it does.
For example if I assume the current flows ccw my equation becomes IR + V - E = 0 which means E=10V. But if the current flows cw my equation becomes IR - V + E = 0 which means E=8V.
