In this episode, we take a look at the shortcomings of measuring low resistances with a standard digital multimeter. We demonstrate measuring a small resistance using both the two-wire and four-wire kelvin methods. Then we build a standalone current source that will be used in conjunction with a standard DMM, allowing us to make four-wire measurements, without an expensive benchtop meter: https://bit.ly/30t9dKj
