The question concearns RLC circuit, i have 2 sets of data, I need to calculate Z (impedance), R (resistance), Xl (inductive reactance), Xc (capacitive reactance), L (inductance) and C (capacitance) for every measurement in the PDF (first pdf is what do those numbers mean, second pdf is the measurement). I do not know how to calculate it, I do not know the formulas to do that. Please calculate it and show me formula how to calculate it. In this pure inductive load, do i need to calculate all the things i wrote above?
