At a lower or higher current, it will have a different. A resistance value isn’t suitable for an LED. A forward voltage is. | |
| Apr 19 at 14:28 | comment | added | Justme | @user3553471 It gets weird because your formulas are weird and do not match the circuit. If you have 3V battery, 2V over LED and 1V over the 100 ohm resistor, that is exactly what the meter shows, 10mA. | |
