Current through the ammeter:
For an ideal ammeter, the resistance is zero.
An idealized ammeter is connected to a battery as shown in the figure (Figure 1).
Part A. Find the reading of the ammeter.
Part B. Find the current through the 4.00-Ω resistor.
Part C. Find the terminal voltage of the battery.
