Yes, pF. :blushing:
I am thinking about another way to measure it. If the output impedance of the function generator is 50ohms, can I use Xc=50=1/2pifC and find this f? Am I looking for -45 phase shift? Thank you.
Thanks for all the suggestions. I tried SRF one, and here is the result.
I know the inductance is about 1.4mH. The inductor was directly connected to the signal generator. The voltage and current across the inductor are measured using scope. I increased the frequency of sinusoid until phase...
