Find imapedance of a circuit with mesured current and voltage and frequency sweep(up to 1MHz). C and L are unknow.

I have a mesured voltage and current. I want to find the impedance magnitude, real and imaginary part then plot yquist and cole-cole plot, but i don't know to proceed, can someone help please.

hello

what kind of measurement process did you use ? sine sweep ?

can you share your data ?

[Alhassane]

here is the value i mesured. Indeed i am using rigol DG1022Z to generate a sine wave with frequency sweep.

[Mathieu NOE]

ok , can you share your data ?

Answer 1

[Star Strider]

By convention, the real part is the voltage, and the imaginary part is the current. Thje phase is the angle between them.

Ohm’s law states

so

At least that is how I understand it.

Also

where X is the reactance (either capacitive or inductive).

Calculating those would be relatively straightforward with your data.
