The picture on the right is the original picture and the picture on the left is where I connected the battery. This is determined by the last digit in my student number which is 3. The A and B which are the wires from the battery are different from the A and B in the circuitboard(I think).

I need to solve for the current in the wire 2 to D. I have no idea how I would do this.

I was helped yesterday with this problem

and I would assume I would have to do something similar but there is no given circuits and current directions.

All the info I get is here in this pdf. (Part 2)

If anyone could give me a nudge I am sure I could solve this.

Thanks,
