Measure inductance using an oscilloscope.

Understand the operating principle of an LCR meter by measuring and calculating inductance and capacitance.

This image shows the equivalent circuit when measuring inductance. On the left is the measurement circuit.
A high precision metal film resistor is recommended for Reference 1kΩ.
The bottom left photo is a photo taken during measurement.
I used the Function Generator below.
This image shows measuring inductance. This image is of an AC oscillator.
The waveform below is the voltage and phase difference of VA1 VA2.
This image shows the oscilloscope waveform when measuring coil inductance, showing the voltage and phase difference between VA1 and VA2.
This image shows the parameters required for inductance calculation. On the left is data obtained from an oscilloscope. 
Calculate impedance and impedance phase angle based on the data obtained from the oscilloscope.
This image shows the impedance and impedance phase angle.
 Calculate Ls Rs.
This image shows the formulas for calculating the equivalent series resistance, reactance, and equivalent series inductance of a coil. This image is the series equivalent circuit of a coil.
Calculate Lp Rp. 
This image shows the formulas for the coil's admittance, admittance phase angle, conductance, susceptance, equivalent parallel resistance, and equivalent parallel inductance. This image shows the parallel equivalent circuit of a coil.
