Calculate impedance in time and frequency?
Not enough time resolution to tell.
But it looks inductive, with noisy current sense and insufficient samples shown,
Try reducing noise with a filter and try an XY scope with the same bandwidth to get the dominant phase. Try DSO FFT.
Current starts with an envelope and reduces with high-frequency noise.
It's better to characterize with a Bode Analyzer or swept amplitude phase response with an output relative to input.
