hello,
i am a first year electrical engenering student. In a school project i try to mesure the skin effect in a wire using à daq my plan is to get both wave forms of voltage and current then i can easely calculate the resistance using my python code as :
R = impedance* cos(phase_shift)
its seems simple but the problem that i had is after trying with multiple wire i had never been able to get a sinusoide ( i got like a periodique form but deformed) . I also tryed to filtrate but i was loosing a lot of precision . maybe my next plan will be to use a wattmeter to get the phase shift but after asking professors there is no wattmeter in our school. Can u please provide me with some suggestion to be able able like to get a sinusoide.
Best regards, .
