What is the function of the inductor in a fluorescent tube light circuit?
Without an inductor in series with the tube, the plasma in the tube would simply short-out the service wires. That would always cause the circuit's protective fuse to blow - or its circuit breaker to trip - to cut off the supply of current to the tube. If that happened the tube light would never be able to perform its intended purpose, which is to continue running - and giving out a continuous light - for long periods of time.So a high-inductance choke must be used in circuit with the starter and the tube for two reasons:firstly the choke generates a high voltage pulse across the tube when the starter's contacts open. That pulse causes the gas in the tube to ionise and become a low-resistance plasma andsecondly, because it is wired in series with the tube, the choke greatly reduces the current drawn by the tube once it contains the low-resistance plasma.The starter is a special kind of switch: its contacts are made of a metal alloy which heats up and bends soon after a voltage is applied, causing the switch contacts to open.
Is tube light run without choke?
No it will not. If you need increase the supply voltage and remove the choke.
Why choke coil is used in tube light?
To limit the current through the lamp when the gas ionises and conducts.
How does fluorescent tube glow?
A fluorescent lamp is a glass tube containing some mercury vapor, with a phosphorescent coating on the interior surface of the tube.The mercury vapor is made to glow by using a high voltage across its electrodes that sets off an electric arc discharge in the tube. The discharge can also be described as a conducting plasma.The resulting flow of current through the mercury vapor is stable and well-controlled by an external ballast, or loading device, which consists of a high-inductance choke-coil that is connected in series with the tube.The continuing dischange glow is invisible to the human eye but it causes the phosphorescent coating on the interior surface of the tube to emit visible light.A fluorescent tube lamp works by using the fluorescence principle. It contains two filaments, one at each end of the tube, which glow to heat up the gas contained inside the tube.The inner surface of the tube is coated with compound of elements having fluorescent properties, such as phosphorus. When it was manufactured all normal air was removed from the tube. In place of the air just a small trace of a gas is put into the tube, such as mercury vapor (for a white color), carbon dioxide (for green), neon (for red color), etc.When the electrical supply is turned on, what happens is that the two filaments glow and then the contacts of the starter open. This action provides a voltage across the tube that is high enough to ionise the warmed-up gas inside the tube. This ionised gas, also called a "plasma", excites the special fluorescent coating on the inside of the tube so that it gives out visible light.Note about the need for a choke and a starterWithout a high inductance choke in series with the tube, the plasma in the tube would simply short-out the service wires.

How does a choke work in a tube light circuit?
The choke works in conjunction with a starter . When you turn on the light , voltage is applied to the choke, and when the switch opens after a few seconds, it creates a high voltage across the contacts at each end of the tube. This starts the ionization of the gas , which glows. Once ionized, it continues producing light even when the voltage applied is only 120 VAC, the power line voltage.
Show you the wiring diagram of tube light fitting with electronic choke?
wiring diagram of electronic choke in tube light
Why is choke connected in parallel to tube light?
choke is connected in series not parallel.lol
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"
What are the parameters of choke coil?
inductance and resistance are the parameters of the choke cil
Does the tube light glow with out starter and choke?
it will not glow
What is the use of choke in the fluorescent tube?
The inductance primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive 'kick' forming a higher-voltage pulse to start the lamp.
What is principle of fluorescent tube light how choke gives transient voltage across tube at the time of starting?
11000
What causes choke in a fluorescent tube light to burn?
There is a coil which converts ac/ to d/c in some models. Sometimes the insulation fails and the wires gets shorted. The wires are covered with a very thin layer of shellac to reduce the size of the ballast and increase inductance.

What is ideal choke coil?
An ideal choke coil has only inductance. It has zero resistance and no stray capacitance, therefore no resonances.
Is tube light run without choke?
No it will not. If you need increase the supply voltage and remove the choke.
