Is ballast synonymous with choke? An electrical ballast (also known as control gear) is a device that limits the amount of current flowing through an electric circuit. When employed in a signal-carrying circuit, a choke is an inductor intended to have a high reactance at a specific frequency. The term "choke" may also be used for other components such as capacitors that limit current flow.
Electrical power transmission lines are usually installed with their outer surfaces grounded to prevent electricity from circulating along them. This prevents lightning from being conducted onto live cables and then into houses via water pipes or otherwise dangerous currents being created within homes. Power companies do this by attaching metal ground wires to all exterior walls of buildings, even if they are not served by that particular company. These ground wires are connected to an earth conductor which is typically attached to a metal frame of the building near its roof. If any part of the ground wire becomes disconnected from the structure it can still conduct electricity if another object is not insulated from the line voltage. This could happen if a person pulls off some of the cable's covering or breaks one of the ground wires.
Electric motors require current to function but they can burn up very quickly if exposed to excessive heat. Unprotected equipment such as motors should never be placed in direct contact with power lines because even if they are not running when you make this connection they will be when you turn on the power next time.
A magnetic ballast (also known as a choke) is made out of a coil of copper wire. The magnetic field created by the wire retains the majority of the current, allowing only the necessary amount to pass through to the fluorescent light. This quantity varies according on the thickness and length of the copper wire. A thin strand of wire will conduct more current than a thick one; likewise, a long piece of wire will not pass as much current as a short one.
The ballast also contains some plastic parts that protect the wire from damage and provide insulation between the segments of wire that make up the coil. These parts include bobbins (on which the wire is wound), cores (pieces of magnetically-permanent material such as iron or steel onto which the wire is wrapped), and terminals (the ends of the wire that connect to the fixture).
The ballast needs electricity to work, so it must be plugged in. When you plug a ballast into a wall socket, the cord attached to the ballast should be long enough to reach from the floor to the ceiling. An electrician can install a special plug called a "competitor" that allows another lamp to be plugged in while still powering the first one. This is useful if you want to replace a lamp without having to turn off the entire room.
Ballasts tend to be rather heavy, usually no less than 1 kilo (2.2 pounds).
The choke's aim is to create a very high voltage between the filaments at first (across the two ends of the tube light). Once the gas in the tube has been ionized, the choke again delivers a low voltage. A choke is a wire coil. Mercury vapor is used to fill fluorescent tubes and lights. It is activated when you switch on the power supply. The mercury vapor begins to glow when it gets the right voltage from the chokes. This is how out-of-balance electric circuits are fixed; the main purpose of the fuse is to prevent excessive current flow through any one section of the circuit. A current-limiting resistor can also be used instead.
Fluorescent lamps require an initial voltage boost (or "choking") before they will light. This voltage boost comes from a transformer called a "choke coil". The function of the choke coil is to raise the voltage level of the power line to a point where the gases inside the lamp will ignite. After the lamp starts, the choke coil provides enough voltage to keep it burning. Some older fixtures have tapered coils which reduce their effectiveness after some time. These should be replaced with flat coils if possible.
The quality of fluorescence depends on several factors including the type of bulb, the length of its life, and how well it is maintained.
