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.

What is the function of the choke in a hpsv lamp?
The function of any ballast in a lighting fixture is to raise the voltage high enough to strike an arc through the bulb or tube.
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"
A choke coil placed in series with an electric lamp in an ac circuit causes the lamp to become dim why is it so?
The light is getting dim because the choke is using the energy the lamp should be using. The purpose of the choke is to remove transients; if it is using power at 50 or 60Hz, this is not desirable. My guess is this lamp is using a new energy efficient (not incandescent) light bulb? If this is the case, don't. If this is a choke you added to the lamp, then perhaps it's the wrong type choke (too large inductance). If you added this, it could be that you inadvertently inserted resistance in the lamp wire. Check to make sure nothing is getting hot around your new wiring. A bad solder point could cause this to some degree.
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What is the functioning of choke coil?
A choke coil is used in several electrical devices. The function it has is to block AC currents from passing through as it allows DC currents to pass through.
What is the function of a choke in a fluorescent lamp?
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.
When you turn on a lamp are you opening or closing a circuit?
Your closing the circuit!
What makes contact with the base of a lamp?
The "hot" conductor of the lamp circuit.
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.
