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.

∙ 12y agoYes it can. However, certain tubes will not fire on just the mains voltage and these are no good with a resistive ballast. T5 types in particular need the high voltage spike from an inductive ballast.
Generally, T12 20W and 40W tubes, and T8 10W and 15W tubes will start with a resistive ballast. It is usually necessary to earth the fitting to help starting. A conventional glow tube starter is used in the normal way.
A resistive ballast has to be used when the mains supply is DC. Special resistance lamps have been made for the purpose, but ordinary incandescent lamps can be also be used, as well as a conventional wirewound resistor.
Commercially made fluorescent lamps with resistor ballasts have been made. Eg. the Mazda Netaline, and also various fluorescent adaptors that plug into an incandescent light socket where the weight of a iron core ballast is problematic.

∙ 8y agoA resistor offers a fixed amount of opposition (resistance) to any current flow through it regardless of changes in the magnitude of the current. A resistor can not store nor dispense electrical energy. A resistor converts electrical power in to heat and releases that heat in to the environment.
A choke (inductor) only offers opposition (reactance) to changes in current flow. A pure inductor offers no opposition to an unchanging current flow regardless of the magnitude of that current. A choke stores electrical energy during an increase in current through the choke and restores electrical energy (come hell fire or high water, ready or not) back into the circuit during a decrease or stoppage in current through the choke. A choke does not, averaged over time, remove electrical energy from a circuit..
About the only thing that a choke and resistor have in common is that the amount of opposition to current flow from each one is expressed in Ohms.

∙ 10y agoYes, you can replace a choke with a resistor. The choke is used as a power supply filter element and tends to work better at filtering than a resistor does.

∙ 11y agoNo. Because the coil is used to store the electrical energy in the form of magnetic
field.

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.
Can you choke on liquids and die?
No
Do ferns choke other garden plants?
nope they do not

What is the cylinder type thing with vent holes at the end of the model 20 12 gauge?
The "Thing" is called a poly-choke. It is a manually adjusted choke. I think they are still in business. And yes I have shot many deer with slugs fired from my Model 20. If you could give a more detailed discription, or perhaps a photo it would be helpful. It may possibly be the Power-Pac choke. That "Thing" is probably a Compensator , and a Varible Choke, or just one of either.
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.

It provides an 'inductive kick' to start the lamp, and also limits current to the proper level after the lamp is started.
How do you reduce the noise in electrical circuits?
Depending on the circuit, typically a combination of a coil (commonly called a choke) and a capacitor can be put in circuit at multiple places to significantly reduce noise in a circuit.
