An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the ...
Fluorescent lamp with an electronic ballast Electronic ballast for fluorescent lamp, 2×58 W Electronic ballast basic schematic Electronic ballasts and different compact fluorescent lamps Electronic ballasts employ transistors to change the supply frequency into high- frequency AC while regulating the current flow in the lamp.
The same report lists the following as some drawbacks to the double-hull design, including more expensive to build, [11] higher canal and port expenses, [11] ballast tank ventilation difficult, [11] ballast tanks need continual monitoring and maintenance, [11] increased transverse free surface, [11] more surfaces to maintain, [11] explosion ...
The adapter consists of a regular bulb screw, the ballast itself and a clip for the lamp's connector. Non-integrated bi-pin double-turn CFL with G24d plug-in base An electronic ballast and permanently attached tube in an integrated CFL. CFLs have two main components: a magnetic or electronic ballast and a gas-filled tube (also called bulb or ...
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
The "strike" requires an electrical circuit with an igniter and a ballast. The ballast is wired in series with the lamp and performs two functions. First, when the power is first switched on, the igniter/starter (which is wired in parallel across the lamp) sets up a small current through the ballast and starter.
NE-2 type neon lamp powered by alternating current (AC) Neon lamp schematic symbol. A neon lamp (also neon glow lamp) is a miniature gas-discharge lamp.The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode).
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
