Measure inductance using an oscilloscope.

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

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.
The waveform below is the voltage and phase difference of VA1 VA2.
On the left is data obtained from an oscilloscope. 
Calculate impedance and impedance phase angle based on the data obtained from the oscilloscope.
