Variable capacitor

OverviewMechanically controlled capacitanceSpecial forms of mechanically variable capacitorsHistoryElectronically controlled capacitanceTransducersNotesExternal links

In mechanically controlled variable capacitors, the distance between the plates, or the amount of plate surface area which overlaps, can be changed. The most common form arranges a group of semicircular metal plates on a rotary axis ("rotor") that are positioned in the gaps between a set of stationary plates ("stator") so that the area of overlap can be changed by rotating the axi…

Working principle of Colpitt''s oscillator

For mechanically stressed resonant circuits, the vote is not a variable capacitor plate. The vibrations do not allow constant capacitance values and hence no proper tuning. In contrast, if a ferrite core is moved along the taut rope through the bobbin so the inductance changes.
