Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...
Capacitors connected in parallel, the total capacitance is the sum of the individual capacitors’ capacitances. If two or more are connected in parallel, the effect is that of a single equivalent ...
T his article is a follow-up to the one on SELF capacitance [1], and together, they cover the theories and design guides for the two most popular capacitive sensors, the projected and self capacitive ...
