It's the 40W tube! because it's nonlinear: indeed it generates harmonics which increase the apparent power and thus the apparent energy.

Why ordinary bulb has short life?
Because an 'ordinary' bulb has a metal filament which glows through resisting the electricity flowing through it. This eventually weakens the filament and it breaks. The 'energy-saver' bulbs are basically miniature fluorescent tubes - these have electrodes at either end of the tube which generate electricity, this 'excites' the molecules of the fluorescent coating - producing light. They only fail when there's no more coating inside the tube - which means they last MUCH longer !
Which bulb is fuse 25w or 100w which is connected in parallel?
Florescent tube
What types of bulbs used for street lighting?
You may use electronic bulb of any kind in your street. It is entirely depends upon your choice but the main thing you should keep in mind that their light should be of white color like tube light. Because it will be more difficult to see things in some other color other then the white one.
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.
Is tube light run without choke?
No it will not. If you need increase the supply voltage and remove the choke.
What energy changes takes place as a tube light is turned on?
utu
Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
What is a dropper and what are its uses?
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
What is a long bulb?
A Tube-light !
What are compact flourecent lamps?
A Compact Fluorescent Lamp (CFL) is type of energy-saving bulb made from a small glass tube which is filled with mercury vapour. It has a phosphorescent coating on the inside of the tube which glows...
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is?
actually, the rare-earth phosphors lining the tube.
Can you light a light bulb by holding a copper tube and a steel tube wired to a light bulb?
no it isn't because of the is it does spell the same thing backwards.
When should you replace a fluorescent light bulb?
when the tube ends blacken after failure of the tube heaters

What are the twisty light bulbs?
These are compact fluorescent lights (CFLs) that produce light but save energy while doing so. In fact, they actually produce more light than a standard light bulb but use less energy while doing so. What makes the CLF different is that the CLF is made from a gas-filled tube and a ballast, while the regular light bulb uses a filament. Hope this answers your question.
What is the glass part of a light?
Tube, bulb, envelope, globe.
