Resistance from Voltage and Current measurement card

[Neolker]

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:
