Hello everyone, I would like to know if is it possible to obtain voltage data with a daq or usb 6009 to calculate ohm law continuously? for example with a variable voltage source, vary the voltage and by means of the daq acquire the voltage data and with matlab calculate the current flowing through a resistance constantly?.

I would appreciate if someone could help me please.

Yes you can acquire voltage data using digital trigger. Following documentation explains how daq command can help you do the same:

I assume that the resistance constant value have been defined and now that shold help you find the current and thus verify Ohms law.
