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.
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.
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.
What is the use of starter in tube light?
Tube light requires two things to function . Very high starting voltage , and high voltage to continue the operation . The starter is a circuit which breaks at regular intervals . When you break a circuit and start again , high voltage spark takes place . This voltage is further amplified through the choke which is a transformer . Thus at the beginning the starter gives high voltage sparks . Due to this the current begins to flow through the tube and the tube begins to glow. Once the tube starts , the required voltage to sustain is quite low , which is provided by the choke .If the starter is bad the tube does not start . If the choke is bad or if the gas is low , the tube does not sustain its light .Fluorescent starters are used in several types of fluorescent lights. The starter is there to help the lamp light. When voltage is applied to the fluorescent lamp, here's what happens:The starter (which is simply a timed switch) allows current to flow through the filaments at the ends of the tube.The current causes the starter's contacts to heat up and open, thus interrupting the flow of current. The tube lights.Since the lighted fluorescent tube has a low resistance, the ballast now serves as a current limiter.When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor.Without the starter, a steady stream of electrons is never created between the two filaments, and the lamp flickers. Without the ballast, the arc is a short circuit between the filaments, and this short circuit contains a lot of current. The current either vaporizes the filaments or causes the bulb to explode.
Can I replace a 230 watt linear halogen lamp with a Watt linear halogen lamp with safety in a flood light?
A 230 watt linear halogen lamp should be replaced by a 230 watt linear halogen lamp if the same brightness is required.
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.
What is a halogen microwave?
There is no halogen microwave. There is a halogen microwave oven bulb. (The technical term for a "bulb" is a lamp.) Some microwave ovens use a halogen lamp to light up the oven cavity. Replacing them is similar to replacing a "regular" incandescent lamp, except that when halogen lamps are being replaced, it is critical not to touch the lamp with bare fingers. Leaving skin oils on a halogen lamp shortens the lamp life and can set up a dangerous situation where the lamp might overheat.
How do you say if xenon lamp or halogen lamp?
xenon(Z NON) halogen(HAL O JEN)
Where can one purchase a Halogen desk lamp?
Halogen desk lamp, Living Access Halogen desk lamp price can be bought from Amazon. Price of the lamp is only 23$ additional 2$ for shipping charge. Which is a great offer.
What is the purpose of halogen gas in a tungsten-halogen lamp?
because somebody didn't answer
How do you change halogen bulb in ls-984 torch reading combo lamp?
It is a double ended halogen bulb and I do not know how to get to it to release it from the lamp.
What day was the halogen lamp invented?
1909
Which lamp consumes more current?
halogen
What size of led lamp will be equivalent to 150 Watt halogen lamp?
LEDs and CFLs use about a quarter of a halogen so the answer is 35-40 watts.
Can I replace a 230watt linear halogen lamp with a 200watt halogen linear lamp with safety?
No problem because the 200 watt produces less heat.
Which floor lamp will tip over the least?
The Halogen Pharmacy Lamp has a no tip base.
