Green Resistor with no writing on a HF Board

[APDahlen]

Hello @tonguis,

Do you have a bench type power supply?

If yes, you could perform a 4-wire measurement to determine the resistance of the wire.

Ref:

Measuring Low Resistance values below 0.1 OHM

There is a test method called the four-wire (Kelvin sensing) connection method which is a method to help measure a low resistance value. These measurements can be made using a DMM, micro-ohmmeter, or a separate current source and voltmeter. In the four wire configuration, the test current (I) is forced through the test resistance (R.) through one set of test leads, while the voltage (VM) across the DUT is measured through a second set of leads called sense leads. Although a small amount of cu…

Please let us know if you have any questions about the procedure.

Best wishes,
