Hello,
I'm completing an assignment for a college class and I'm seeing some very strange readings on one of the ammeters. As you can see form the picture, its a simple series circuit with a supply voltage of 12VDC and 12k ohms of resistance. I expect to see 1mA of current at any point in the circuit and yet, an ammeter placed between R1 and R2, continues to shows .998mA. I've tried deleting and re-adding the ammeter, swapping ammeter positions, and even have only the the one ammeter between R1 and R2. Any ammeter placed between R1 and R2 shows .998mA instead of 1mA. An ammeter placed anywhere else in the circuit shows correctly. I have used a multimeter to measure as well and it shows the correct value of 1mA when connected between R1 and R2. Has anyone had experience with an issue like this or have any recommendations? Thank you in advance.
Edit: Additionally, I changed R1 to be 2k ohms instead of 1k ohms and changed R2 to be 1k ohms instead of 2k ohms (reversed their values), and now the ammeter between them reads 1.002mA.
Solved! Go to Solution.

Слегка загрубите внутреннее сопротивление, и всё у вас получится...
Установки моделирования-стандартные...

Okay so this is just expected behavior then.
I adjusted the internal resistance of the ammeters until they all just showed 1mA.
Thank you!
