There is a coil which converts ac/ to d/c in some models. Sometimes the insulation fails and the wires gets shorted. The wires are covered with a very thin layer of shellac to reduce the size of the ballast and increase inductance.

What causes transformers to burn up?
the heat formed in the core due to the "eddy currents" burns a transformer
Can a light bulb cause fire?
Yes it can. If a light bulb breaks, the exposed filament will burn out within a couple of seconds and can ignite something with the spark when the filament breaks. Special bulbs can be made for explosive environments to minimize the risk of ignition, such as lighting at a refueling station. A light bulb can also be in close proximity to a combustible substance when it is operating and can cause a fire by making the combustible substance too hot. Florescent lights are less likely to cause fires because they run cooler and are safer in hazardous environments where a conventional light bulb would not be good. <<<>>> No. The filament will burn out in milliseconds not seconds and not enough time to ignite anything in a normal atmosphere. Special bulbs are not made for explosive environments it is the fixture that the bulb goes into that have the explosion proof rating. Fluorescent lamps in hazardous environments again are protected by the fixture that they are installed into. If the light bulb breaks the filament will be exposed to oxygen in the air and burn itself open. It is when the light bulb is in close proximity to a combustible substance when it is operating, that a fire hazard becomes a reality.
Why the fluorescent lamp turns to black in colour at each ends when it is fused?
The tube has wire filament heaters at each end like flashlight bulbs.The heaters glow when the light is switched on and ionise the gas inside.The ionised gas is subjected to a high voltage and a plasma ( like a lightning bolt) flows from end to end. The excited plasma causes the white powders on the inside of the glass to glow. When the filaments burn out they blacken the ends with metal oxide and it is then almost impossible to get the plasma started again without hot filaments glowing. 1-2000 volts would then be needed
Why does Fluorescent bulb not light and end turns black?
In order to know why fluorescent bulbs turn black at the end, you need to understand how they work. Basically, when you turn on the lighht switch, the ballast sends a spark through the mercury-vapor-filled tube or bulb, depending on design. When it does this, it creates light by activating phosphors that coat the inside of the tube. Well each time the ballast fires, it creates emissions. These emissins materials then settle on the surface inside the glass. After awhile this material piles up. When it does this, the tube end turns completely black. Not only does the tube end turn black, but the accumulated materials pile up so high that it blocks the electrons that flow into the mercury. When this happens, you will notice the bulb or tube flicker heavily and then burn out.
Is a 110 rated light fixture different from a 220 rated light fixture?
no but connector used in 110 rated have to be different in 220 rated system ------------------------ They are very much different. If you place a 110v rated fixture on a 220v circuit, all else being equal, you will double your current flow and odds are it isn't designed to carry twice the current. It will burn out. On the other hand, if you place a 220v rated fixture on a 110v circuit, all else being equal, you will only draw half as many amps as it is designed for and likely won't get any light. It won't burn out, but it almost certainly won't work. There are many fluorescent light fixtures that are rated for more than one voltage, however. They have internal mechanisms that allow you to connect them to different voltages and still work properly. But the fixture still has to be rated for the voltage that you connect to it. The first answer above is correct in that cord and plug connections in the same installation (home, building, business) must be different for different voltages.
You do not burn your finger when you touch a tube light?
If it's fluorescent, no.
Can higher voltage burn the fluorescent bulbs?
it all depends on the voltage the light bulb can sustain.
What causes firewood not to burn?
You forgot to light it?
What causes black spots on fluorescent bulbs?
Normal wear and tear from arc welds when bulb is becoming deteriorated. replace if you don't to wait till they burn out on their own.
Do meteors produce their own light?
In the sense that atmospheric friction causes them to burn, yes.
Do you light up fire workers on Diwali?
Fire works should not be burn. It causes pollution.
What do people burn for fuel?
People burn fossil fuels to get the energy stores in then the energy then causes the engines to run.Help to cook food.Help to light the surroundings.
What causes the streak of light observed when a meteoriod enters Earth's atmosphere?
The friction with the Earth's atmosphere causes a meteor to heat up and burn.
What is the best amount of sunlight and water for growing violets?
The best light is either fluorescent light or natural indirect light, not direct sunlight or your plants will receive burn marks. Keep plants moist, let dry out a tiny bit then water them again.
What causes the sun to burn?
hydrogen is at the heart of a star, meaning that as it reacts it produces a massive amount of heat and light
