A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
Cylindrical Capacitor
What is a Cylindrical Capacitor? A Cylindrical Capacitor is made up of two coaxial cylinders, one inside the other, separated by a dielectric material. The inner cylinder is usually a solid conductor, while the outer one is a hollow cylinder.
