The gas in the fluorescent tube has a high resistance when not lit, so it takes a high voltage to start it glowing. The "starter" stores energy and releases it all at once, causing a high voltage. Once the tube is glowing its resistance is lower, so it can continue to run without the starter. In fact the mains voltage is much higher than the tube requires to run once the gas inside it has been "lit" by the starter. A special thing called a "ballast" is included in the lamp fitting to reduce the mains voltage to one that is sufficient for the lamp to run continuously without overheating. If there was no ballast in the circuit supplying the lamp, the tube could get hot enough to explode!

∙ 13y agoThe function of a starter is mainly to provide the high potential difference required to to start the flow of electrons in the lamp.Whereas the choke is manly used to maintain the potential difference between the electrodes to keep the flow of electrons constant so that the lamp works without any interference.

A motor starter is a piece of equipment that incorporates various components necessary to control the operation of a motor. Common components include:
Disconnecting means
Motor Relay (sometimes called a starter by itself)
Control wiring
Overload protection
The control wiring is the interesting part of a motor starter. Anything that is necessary to determine if or when a motor runs is wired into various relays and interconnects contained inside, attached to, or in close proximity to the motor starter.
A motor starter will usually have what is called a hand/off/auto (h/o/a) switch on the front of it. This switch in the off position means the motor will not run; it is off. The hand position is what you and I might call the on position; the motor is going to run regardless of what the controls are saying. In the auto position the motor will run only when the the controls tell it to do so.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can a single pole switch replace a starter in a fluorescent lamp?
No, a starter must be used.
Can we use fluorescent lamp in dc?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
Functions of choke and starter in a fluorescent lamp?
It provides an 'inductive kick' to start the lamp, and also limits current to the proper level after the lamp is started.
If the ballast on a fluorescent light blows will the lamp still work?
If the ballast on a fluorescent light blows the lamp will not work.
What does CFL's in lighting stand for?
The fulform of CFL bulbs is compact fluorecent light

A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor

What is the necessity of the starter in fluorescent lamp?
When line voltage is applied across the starter, it closes a circuit, connecting the filaments at the ends of the bulb in series so they heat up. Once the Mercury in the lamp is vaporized, the starter breaks the filament circuit, and the ballast provides a voltage pulse to start the current flow down the length of the tube, lighting it. While the bulb is lighted, the voltage across the starter is low and it does not energize the filaments. When you see a fluorescent lamp flashing, the bulb is worn out and the starter keeps vainly trying to start it. Eventually the starter will wear out and will need to be replaced also. Newer fluorescent fixtures have lamps and ballasts that do not require a starter.

What would be the effect on the circuit should the starter be taken out the lamp is started?
Once started the fluorescent tube no longer needs the starter. In fact starters are designed to electrically "remove" themselves from the circuit when the fluorescent tube is conducting.
Why do you use starter for an incandescent lamp?
The starter will send a delayed high voltage electricity to the gas within the fluorescent bulb that cause the gas to be ionized and conduct electricity.
