Very logical explanation on low calue C3

Any clear logical explanation on the function of C3 sides the C of device under test ?

It's simply a coupling capacitor - only a low value is needed, as you test ESR at 100KHz.

Passing AC and blocking DC.

It couples the signal from one stage to the next stage.

If you know zero about electronics why are you looking at building an ESR meter?.
