What is tungsten bulb?
A tungsten bulb is a common lightbulb, the fillamint in a bulb is the small wire in the middle that's drawn across the two contacts. This wire provides an electrical resistance and heats up and this generates light. In a common lightbulb all the air must be taken out and replaced with an inert gas to stop the tungsten fillament burning away.
Can one replace a tungsten bulb with a compact fluorescent bulb?
Yes, if it fits the socket and the light fitting, or lamp fixture, with its cover or shade. You will not be able to dim the compact fluorescent as you did the incandescent (unless you have a really fancy dimmer).
Why tungsten wire used in domestic wiring and why?
Tungsten wire is not commonly used in domestic wiring. It is more commonly used in applications such as incandescent light bulbs, electronic components, and heating elements due to its high melting point and resistance to corrosion. Instead, copper wire is typically used in domestic wiring due to its excellent conductivity and cost-effectiveness.
Why is the earths history divided into long units of time?
So you can understaned it much more better and think about it!
Do earths oceans gain or lose water considering evaporation and condensation?
An equilibrium exist on long term.
What is the long form electron configuration of tungsten?
The long form electron configuration of tungsten is Xe 4f14 5d4 6s2.
How long is the world's supply of tin going to last?
1 second
About how long ago was the last time earths magnetic field reversed?
About 41,000 years ago.
How long does a volt last if only given a volt?
Zero time after the supply is diconnected.
How long will the supply of coal last?
The global supply of coal is estimated to last for several hundred years, depending on consumption rates and reserves. However, the shift towards renewable energy sources and increasing focus on reducing carbon emissions may impact the long-term demand for coal.
Why not iron filament used in bulbs?
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
Why did the crusades last so long?
You had to gather your army, supply it and then travel (by land or ship) to the Holy Land.
What brand of power supply last the longest?
GE is known for its reliable and long lasting power supplies.
How long will oxygen last At current rate of burning?
The duration of oxygen supply depends on factors such as the volume of oxygen available and the rate of consumption. It would be best to calculate this based on specific data about the oxygen supply and rate of burning.
What are light bulb filaments?
Usually Tungsten. Carbon filaments were used first, but scientists found that tungsten works for a far longer time period. Unfortunately, most filaments designed today don't last near as long as the bulb is rated at. Just put a dated replacement sticker on a light bulb and see when the next time you replaced it how long it went. You will be surprised.
In gas tungsten-arc welding a long electrode extension is highly desirable true or false?
False, this will cause contamination of the tungsten electrode as there will be insufficient gas coverage.
How long does a incandescent light bulb last?
It depends on the quality of filament, how often it is switched on and off and fluctuations of supply voltage.
