Why is choke connected in parallel to tube light?
choke is connected in series not parallel.lol
Which material are used in tube light starter?
Bi Metallic
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.
How do you fix a broken tube light have done the usual - on off button got new tube light banged slapped cursed the framing moved the wires - nothing any ideas what could be wrong?
If you refer to a flurecent tube you need to check the starter if it has one (small round tube in the side of the light), check the fuse box for that light, check the switch for that light and check that the tube youve banged about has not also blown i.e. check in another tube socket if possible
Why would a tube light be flickering?
Most likely it is coming to the end of its life (you can see this if the ends are darkened) or it could be the "starter" that need replacing.
Does a tube light glow without starter?
yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.
Is tube light run without choke?
No it will not. If you need increase the supply voltage and remove the choke.
Will the tubelight glow if the starter is removed?
No, the tubelight will not glow if the starter is removed. The starter is necessary to provide the initial surge of voltage needed to ionize the gas inside the tube and establish the electric arc that produces light. Without the starter, the circuit will not be able to function properly.
Where is the position of capacitance of tube light?
The small cylindrical thing that You see (generally on a side of the choke coil) is the "starter " of the tube light. This is the capacitor used in tube light. And is used to provide a momentary voltage rise of nearly 400V to start up the tube light hence Starter.
Show you the wiring diagram of tube light fitting with electronic choke?

Why does the starter not strike after it has established the glow in the tube?
The starter does not strike after establishing the glow in the tube because it is designed to operate only during the initial phase of starting the fluorescent lamp. Once the gas in the tube ionizes and allows current to flow, the starter automatically disconnects from the circuit. This prevents it from interfering with the normal operation of the lamp, allowing the ballast to regulate the current and maintain the light output.
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 inductance of tube light choke?
0599H
Why is choke connected in parallel to tube light?
choke is connected in series not parallel.lol
What is inside the tubelight?
the supplied power will be mainly increased with the help of a choke.....and the starter will be present inside the tube light...the main function is to make and break the circuit.....instead of a stater a small wire can also be placed in the place of a starter.......the ionization mainly takes place in the tube light...
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.
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. 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.The starter is a special kind of switch: its contacts are made of a metal alloy which, soon after a voltage is applied, heats up and bends, causing the switch contacts to open.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.For more information see the Related link below and the answers to the Related Questions.
