What is the function of a starter in a fluorescent lamp?

Answer 1

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!

Answer 2

The 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.

Answer for USA, Canada and countries running a 60 Hz supply service.

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.

Answer 4

The ballast throttles the current by way of self inductance. The starter temporarily by passes the lamp ends and enables the current flow through florescent material of the tube. This action causes the start of current in fluorescent light fixture for the required glow.

Answer 5

The starter in a fluorescent lamp is responsible for initiating the flow of electricity through the lamp. It helps to preheat and ionize the gas inside the lamp so that it can produce light efficiently. Once the gas is ionized, the starter shuts off and allows the lamp to continue operating normally.
