OverviewCapacitor typesHistoryTheory of operationNon-ideal behaviorCapacitor markingsApplicationsHazards and safety
Practical capacitors are available commercially in many different forms. The type of internal dielectric, the structure of the plates and the device packaging all strongly affect the characteristics of the capacitor, and its applications. Values available range from very low (picofarad range; while arbitrarily low values are in principle possible, stray (parasitic) capacitance in any circuit is t…
