  2. Motor capacitor - Wikipedia

    en.wikipedia.org/wiki/Motor_capacitor

    A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...

  3. AN/ARC-5 - Wikipedia

    en.wikipedia.org/wiki/AN/ARC-5

    VHF transmitter T-23/ARC-5 and HF transmitter T-20/ARC-5 on rack MT-71/ARC-5. The AN/ARC-5 Command Radio Set is a series of radio receivers, transmitters, and accessories carried aboard U.S. Navy aircraft during World War II and for some years afterward. It is described as "a complete multi-channel radio transmitting and receiving set providing ...

  4. Electrical ballast - Wikipedia

    en.wikipedia.org/wiki/Electrical_ballast

    An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on.

    AN/ARC-38: HF AM transceiver: Collins Radio: AN/ARC-65: HF radio communication system replaced AN/ARC-21, added Single-sideband modulation (SSB) AN/ARC-133: Ultra high frequency (UHF) Radio communication system, pressurized version of AN/ARC-34: AN/ARC-164: Ultra high frequency (UHF) radio communication system: AN/ARC-182

  6. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    In schematic diagrams, a capacitor used primarily for DC charge storage is often drawn vertically in circuit diagrams with the lower, more negative, plate drawn as an arc. The straight plate indicates the positive terminal of the device, if it is polarized (see electrolytic capacitor ).

  7. List of RF connector types - Wikipedia

    en.wikipedia.org/wiki/List_of_RF_connector_types

    DIN 7/16 connector (DIN 47223 and IEC 61169-4 [1]), a high-power 50 Ω connector originally developed by Spinner [2] F-type connector, used for domestic television installations and domestic satellite LNBs (75 Ω) worldwide with the exception of Europe and Australia; GR connector (officially the General Radio Type 874)

  8. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    In this case, they are called grading capacitors. In schematic diagrams, a capacitor used primarily for DC charge storage is often drawn vertically in circuit diagrams with the lower, more negative, plate drawn as an arc. The straight plate indicates the positive terminal of the device if it is polarized (see electrolytic capacitor).

  9. Balun - Wikipedia

    en.wikipedia.org/wiki/Balun

    Isolation transformer. In classical transformers, there are two electrically separate windings of wire coils around the transformer's core. The advantage of transformer-type over other types of balun is that the electrically separate windings for input and output allow these baluns to connect circuits whose ground-level voltages are subject to ground loops or are otherwise electrically ...
