I've started working on capacitive sensors and finally got one ready(which is concentric cylinder type) but now I need to test it. I have few doubts:
- Can I calculate the value of capacitance without any instrument?
May be just with an analytical formula. - What difference I may get in the values of capacitance produced from this formula and from an LCR-meter?

Or better yet: R is for bias current and should be large.
