Why halogen lamp is not required the choke and starter?
saanu ki pta
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.
Why choke coil is used in tube light?
To limit the current through the lamp when the gas ionises and conducts.
What is the function of a capacitor in a fluorescent light fitting?
A capacitor is used to improve the power factor of the lamp.More detailsTo prevent the lamp from taking too much current a fluorescent lamp has to have a choke, which has magnetic inductance. The inductance has a negative impact on the power factor of the (the ratio between apparent power and real power taken by the lamp) - i.e. the power factor is reduced - so a capacitor is used to compensate for the inductance by improving the power factor so that it is closer to the ideal value of 1.Basically the inductor with the capacitor smooths out the voltage or current.
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.
