    In case anyone else is having the same confusion I found an explanation for this. https://electronics.stackexchange.com/questions/76367/accounting-for-led-resistance/76372#76372?newreg=ae8bec16116449b38b8b3f548d004072 Turns out LEDs do have a voltage drop but not a constant resistance like resistors. Instead they tend to keep the voltage drop stable. That's the reason when the resistor is 1 microOhm the LED also seems to have almost no resistance and the total Resistance becomes so small that the...

    Also when I think about it, the total resitance on the circuit is so small that the ammeter's resistance may have been taken into account. However that is the least of the problems I have. The main thing that concerns me is that the led has next to zero resistance. This almost makes sense to me since it's a diode but I don't think that is the case with real LEDs

    When I connect an LED and an Ammeter serial to a 9V battery, the Ammeter shows 13.2 kA. If I add a 1 microOhms resistor serial to the rest, the Ammeter shows 4.06 MA. Also the LED has 1.29V between each side and the resistor has 4.06V which doesn't add up to 9V. I tried to tweak the LED but the properties I can adjust are breakdown voltage, color, emission coefficent and saturation current none of which seems to change the readings on anything. Normally a 9V battery, a standard LED and a 300 Ohms...
