The tube is filled with noble gas (i.e. argon, neon, helium).
The tube also contains a small amount of Mercury that when heated becomes mercury vapor.
The inside of the tube is lined with phosphorescent material (mostly phosphorous).
In the base of the bulb is an electronic ballast that boosts the line voltage up high enough to ionize the gas inside the bulb. As this happens the mercury also vaporizes inside the tube.
The ionized gas and ionized mercury vapor emit ultraviolet light which strikes the phosphorous. The phosphorous, in turn, emits white light that lights up the room.
Fluorescent lamps can reach temperatures between 150-250 degrees Fahrenheit during operation. The heat is mainly generated by the electrodes and the ballast of the lamp. It is important to handle fluorescent lamps carefully to avoid burns.
The principle that concentrates the effects is called the Mass Principle of War. It concentrates the effects of combat power for the best results.
No, rheostats are not typically used with fluorescent lights. Fluorescent lights require a specific type of ballast to control the current and voltage, which is different from the functionality of a rheostat. Using a rheostat with fluorescent lights can lead to inefficient operation and potential damage to the lights.
Yes, it is important for the wattage of the fluorescent ballast to match the wattage of the fluorescent tube. Mismatched wattages can result in inefficient operation, reduced lifespan of the bulb, or even damage to the ballast. Always make sure to check and use the appropriate wattage for both the ballast and the tube.
No, a fluorescent light fitting typically requires a capacitor to function properly. The capacitor helps to regulate the electrical current and improves the efficiency of the light, ensuring stable operation and reducing flickering. Without it, the fluorescent lamp may not start, or it could flicker and have a shorter lifespan.
principle refers to the basic objective of something. Operation refers to how it operates.
it shines more brightly
Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)
Give a brief idea of principle of hysteresis motor,application.

The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.
The principle of operation involves using a fan mounted in the top of the cabinet to draw a curtain of sterile air over the products that are being handled.
The purpose of a fluorescent light ballast is to regulate the electrical current flowing through the fluorescent light tubes. It provides the initial surge of electricity needed to start the light and then regulates the current to keep the light glowing steadily. The ballast also helps prevent flickering and ensures the longevity of the fluorescent tubes.
