In Real Life, the resistance of an ammeter is very low - probably under 0.05 ohms, however, I would expect the simulator's ammeter to have a resistance of zero. If the meter resistance is zero, and you have it connected across your .321 ohm resistor, the only remaining resistance in the circuit is the 1.44 ohm, so the current in the circuit is 12/1.44 = 8.33 amps. By the way, Linear Technology has a very nice free simulator called "LT Spice" available for download. Yes the meter is set to 1nm. I forgot that electricity will take the path of least resistance so with the ammeter resistance being near 0 it simply allows the current to bypasses the .321 resistor leaving only the 1.44 in the circuit. Thanks for clearing that up. ```
