Perhaps a better explanation is required.
It appears to me that the boxes along the top are Amp Meters, and they all read the same thing.
Do you have any additional note or details about the circuit?
Which component(s) do you expect?
Edit: This certainly appears to be Homework Help, please put this in the homework section next time.

Assuming the boxes are ammeters (gryd3's post #2), each box could be replaced by a short circuit as an ideal ammeter measures current without introducing any additional resistance into the circuit (note that real ammeters do have a resistance). In that case a short of any of the resistors R1...R4 would cause an infinite current from the voltage source through all ammeters to the left of the shorted resistors. The ammeters to the right of the shorted resistor would see a current of 0A because the voltage across the short circuit is 0V.
The task description is not well done. Here are a few issues:
The ammeters obviously do not have 0Ω resistance, otherwise current would be infinite in a short circuit situation.
Infinite current is indicated by the ammeters showing 2.400 GA. Quite a lot but not infinite.
No indication is given as to the "quality" of the components. Are ideal components to be used (e.g. ammeters and voltage source having 0Ω resistance) or real ones (ammeter's or voltage source's resistance > 0Ω)? Obviously the latter but without clear detail.
