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 ...

Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. C = Q/V = ε A/d = ε0 εr A/d The ability of a capacitor to store maximum ...

Capacitance-voltage (C-V) testing is widely used to determine semiconductor parameters, particularly in MOSCAP and MOSFET structures. However, other types of semiconductor devices and technologies ...

If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...
