A circuit is setup with an ideal ammeter connected across the 4.0 ohm. What will the reading of the ammeter be?
2. The attempt at a solution
I am not sure whether the question is testing my understanding on how an ammeter should be connected in a circuit or about how to simplify circuits. I know that an ammeter must be connected in series in a circuit, but I cannot tell whether the one in the diagram is connected so. Or do I need to simplify the circuit such that the parallel-series combination of the circuit is more apparent?
