As Electronaut says, the arrow that is displayed when you hover over the component indicates which way the current flows when you probe it. As bad luck would have it, it always displays in the opposite you way you want it. However, if you go to the plot window and right click over the plot icon you can put a '-' sign in front of the icon and it will invert the current, so you can change the current flowing into a node into a current flowing out of that node. Hope this helps - Simon
