fluorescent lamp work on the principle of ionizing the gas , which requires very high potential difference . this excess voltage is provided by the choke coil . when the starter breaks the circuit , current suddenly drops , thus to maintain the current the choke coil a very high voltage is supplied by the choke coil . this very high voltage cannot be obtained from a resistor or a rheostat , since it being a linear element , thus it cannot be a replacement for choke.

Functions of choke and starter in a fluorescent lamp?
The choke is used to limit the current flowing through the fluorescent lamp during start-up, allowing the lamp to warm up gradually. The starter is responsible for providing the initial high-voltage kick needed to start the lamp by ionizing the gas inside the tube. Together, the choke and starter work to regulate the flow of electricity and provide the necessary conditions for the fluorescent lamp to operate efficiently.
What is Single phase choke coil?
Choke coils have a piece of wire wrapped around an iron core and their purpose is to allow a low frequency (typically 60 Hz) to pass, while blocking higher frequencies. Choke coils provide electronic circuits with protection from fast events (like a lightning or similar discharge on the power wires) by acting as a shunt to events whose frequencies are above the intended range.
Bolens Mower with a 4.5HP B and S Engine What is the correct spring configuration on the choke assembly?
I recently replaced my springs. There is a shorter one that's closer to the engine and a longer one that goes at a diagonal. The problem I'm having is that they seem to stretch out quickly so they don't really work efficiently. I'm looking for the owner's manual PDF (again) online and I'll post it here when I find it.

If a man breathed in particles of sawdust what might happen to him?
he could choke
How do you use smoulder in a sentence?
The thick smoldering smoke of the fluorescent fire was enough to make him choke.
What is function of the choke in lamp circuit?
The function of a choke in a lamp circuit is to produce high voltage. In tubelights, the high voltage is essential for ionisation of the gas which is present in tubelights.
How will you test starter and choke in fluorescent tube?
You can use a wire instead of the starter to test the tubes .. I did it, it works !
What is quality factor for choke coil?
the quality factor for choke coil is impedence divided by resistance in a given circuit
What is principle of fluorescent tube light how choke gives transient voltage across tube at the time of starting?

What is the function of choke in tube lights?
To limit the current flowing through the fluorescent tube once its gas has ionised.
Working of choke in tubelight?
The choke works as an inductor(filter) induced 850V to 1100V in starting,by strarter make and break of the circuit. After glowing the tube light choke work as inductance and provide 110v to circuit, here the function of starter comes. It helps the chocke to brek from the circuit and to 110v from 850V.thankining U "Nikki"
Why now-days fluroscent light does not has choke and starter?
it have electronic inverter circuit
What is the difference between transformer choke and ballast?
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled wires. A changing current in the first circuit (the primary) creates a changing magnetic field; in turn, this magnetic field induces a changing voltage in the second circuit (the secondary). By adding a load to the secondary circuit, one can make current flow in the transformer, thus transferring energy from one circuit to the other. A choke is an inductor designed to have a high reactance to a particular frequency when used in a signal-carrying circuit. An electrical ballast (sometimes called control gear) is a device intended to limit the amount of current flowing in an electric circuit. Ballasts vary greatly in complexity. They can be as simple as a series resistor as commonly used with small neon lamps. For higher-power installations, too much energy would be wasted in a resistive ballast, so alternatives are used that depend upon the reactance of inductors, capacitors, or both. Finally, ballasts can be as complex as the computerized, remote-controlled electronic ballasts used with fluorescent lamps.

How choke coil limit current to the fluorescent tube?
A choke coil, also known as a ballast, limits the current to a fluorescent tube by providing a high impedance to the flow of current. This high impedance restricts the current flowing through the tube, allowing it to operate within its required current range. The choke coil also helps regulate the starting voltage and stabilize the operation of the tube.
What is choke coil?
A choke coil is an inductor, which is designed to block a particular frequency in an electrical circuit while passing signals of very less frequency or direct current.
