Homework Help: Help with Protoboard & connecting ammeters

Hi,

I'm working on a pre-lab right now, and I'm confused about how to connect an ammeter so that it measures the current going through an individual resistor (where there are two resistors in parallel.)

This is what an empty http://img23.photobucket.com/albums/v68/AngelOfMusic/emptpy.jpg [Broken] .

However, I'm not sure how to connect the ammeter so that it measures the current of the individual resistor instead of the total current. (We are not given resistance so we must have the current. We are not allowed to use an ohmmeter at this step of the lab.)

Here's the layout I have so far: http://img23.photobucket.com/albums/v68/AngelOfMusic/protoboard.jpg [Broken]

But as far as I can see, this only creates this circuit: http://img23.photobucket.com/albums/v68/AngelOfMusic/circuit.jpg [Broken]

Anyone know where I'm going wrong? I'm having trouble seeing where else I could connect the ammeter.
