Hi,
Conducted the experiment.
Took two capacitors and measured their value.
It turned out that C1 = 2.571 (nominal 2.2) pf, C2 = 2.803 (denomination 2.7) pf
Incorporated them sequentially, measured C12 = 1.41 pF
Calculation of C12 = 2.571 * 2.803 / (2.571 + 2.803) = 1.34 pF
The measurement error is (1.41-1.34) /1.34 more than 5%.
Why such a big error?
Thank you
