  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. 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.

  4. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  5. Fluorescent lamp - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_lamp

    A 65-watt fluorescent lamp starting on a semi-resonant start circuit A semi-resonant start circuit diagram. The semi-resonant start circuit was invented by Thorn Lighting for use with T12 fluorescent tubes. This method uses a double wound transformer and a capacitor. With no arc current, the transformer and capacitor resonate at line frequency ...

  6. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    These 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).

  7. AN/ARC-5 - Wikipedia

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

    The most common AN/ARC-5 receiver remote control box is the C-38/ARC-5, which allows control only of audio volume of the VHF and MF/HF receivers. No power, mode, or frequency controls are present. The C-38 also has controls for the R-4A homing receiver. A common AN/ARC-5 transmitter control box C-30A/ARC-5 has controls for selecting the MF/HF ...

  8. Mercury-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Mercury-vapor_lamp

    The reason for a prolonged period of time before the lamp restrikes is to due the elevated pressure, which leads to higher breakdown voltage of the gas inside (voltage needed to start an arc – Paschen's law), which is outside the capabilities of the ballast. Because of this, many mercury-vapor lamps have a secondary lamp to function as a ...

  9. 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).
