2. Capacitor types - Wikipedia

   en.wikipedia.org/wiki/Capacitor_types

   100/120 Hz for electrolytic capacitors; 50/60 Hz or 100/120 Hz for non-electrolytic capacitors with C R > 10 μF; For supercapacitors a voltage drop method is applied for measuring the capacitance value. . Capacitors are available in geometrically increasing preferred values (E series standards) specified in IEC/EN 60063.

3. Dissipation factor - Wikipedia

   en.wikipedia.org/wiki/Dissipation_factor

   The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or

4. Utility frequency - Wikipedia

   en.wikipedia.org/wiki/Utility_frequency

   The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.

5. Vacuum variable capacitor - Wikipedia

   en.wikipedia.org/wiki/Vacuum_variable_capacitor

   A vacuum variable capacitor. A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume.

6. Electrolytic capacitor - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_capacitor

   An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor.
