Hello everyone, is it possible to calculate resistance from voltage and current measurement card?
My configuration is:
Baseboard: IN cDAQ-9178
Voltage: IN 9221
Current: IN 9227
Thanks you in advance.

Hi Neolker!
Sure it is possible, the only thing you'll need is a source (voltage or current), since the resistor is a passive component. Drive your resistance through your source, and measure both the voltage that the source provides, as well as the current flowing through. Here's a good document on the subject.
Kind regards:
