    Working on this lab and I think I have everything down except the Currents: I8, I9, I10. Im looking near resistor 5 and it seems to have arrows going in 2 directions. Is that right?

    thanks.

    Whether it is correctly labeled or not, the current will just have the opposite sign for directlion. The arrow pointing up doesn't seem to have a label though.

    i think u r wrong ~~
    most of arrows i your picture i think is wrong~
    current flow from node with high voltage to lower .

    Cause no current would flow in two directions,I agree with littlefan

    Current "flows" in whichever direction you specify on your diagram. It might be negative (in the opposite direction as the arrow), but you can still calculate it.

    On the other hand, real electrons flow in the direction OPPOSITE to which we normally consider current to flow -- towards the lowest electrical potential.
