Solving Circuit with Ideal Ammeter: 4.0 Ohm Resistance

AI Thread Summary
The discussion revolves around determining the current reading of an ideal ammeter connected across a 4.0 ohm resistor. Participants express uncertainty about whether the problem tests their understanding of ammeter connections or circuit simplification. It is clarified that an ammeter should be connected in series, but the current must be calculated based on its actual connection in the circuit. The suggestion is made to replace the ammeter with a wire of no resistance to simplify the analysis. Ultimately, the focus is on calculating the current despite the improper connection of the ammeter.

Homework Statement


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?

An ideal ammeter can simply be replaced by no resistance wire for solving circuit related problems .Replace the ammeter by no resistance wire and then try to solve it.

Yes, the ammeter is not connected in the proper way, but you have to calculate the current through it as it is. Do what harsh_sinha said.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
