The SI unit of capacitance is the farad (symbol: F), named after the English physicist Michael Faraday. [2] A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates. [3] The reciprocal of capacitance is called elastance.
A gimmick capacitor is a capacitor made by twisting two pieces of insulated wire together. The capacitance may be varied by loosening or tightening the winding. The capacitance can also be reduced by shortening the twisted pair by cutting. The available capacitance is on the order of 1pF/inch (0.4 pF/cm). [1]
The simplest switched-capacitor (SC) circuit is made of one capacitor and two switches S 1 and S 2 which alternatively connect the capacitor to either in or out at a switching frequency of . Recall that Ohm's law can express the relationship between voltage, current, and resistance as:
The change of capacitance for P 100 and N 470 Class 1 ceramic capacitors is lower than 1%, for capacitors with N 750 to N 1500 ceramics it is ≤ 2%. Film capacitors may lose capacitance due to self-healing processes or gain it due to humidity influences.
A feedthrough capacitor is a component that, while not serving as its main use, has capacitance and is used to conduct signals through a conductive sheet. Several other types of capacitor are available for specialist applications.
A gimmick loop is a simple type of capacitive coupler: two closely spaced strands of wire. It provides capacitive coupling of a few picofarads between two nodes. Usually the wires are twisted together. [4] [5]

Jump wire material for ready-made or homemade wires should usually be 22 AWG (0.33 mm 2) solid copper, tin-plated wire - assuming no tiny plugs are to be attached to the wire ends. The wire ends should be stripped 3 ⁄ 16 to 5 ⁄ 16 in (4.8 to 7.9 mm). Shorter stripped wires might result in bad contact with the board's spring clips ...
