From my FB comment
Some comments say measure with a meter, but fractional ohm resistors don’t measure, or barely measure with the typical ohmmeter. Instead, you should be giving better advice. You should use the device between your ears to find the resistance.
The resistor should be put in series with another resistor of a known value, say a 100 ohm resistor. Then connect both across a variable DC power supply, and set it so there’s 10 volts across the 100 ohm resistor, which gives 0.1 A through both. Then measure the voltage across the unknown resistor. Divide it by the current, 0.1A, and you should have the value of the unknown resistor. Simple.
