The external electrode fluorescent lamp according to claim 1, wherein the ferroelectric glass tube has a dielectric constant of about 1020.3. The external electrode fluorescent lamp according to claim 1, further

Which is a type of Electrically-Erasable Programmable Read-Only Memory

://en.wikipedia.org/wiki/E EPROM...An electrically programmable read only memory device accumulates electrons in a floating gate electrode so as to change the threshold level at a first control gate electrode capacitively coupled with the floating gate electrode, and a second control gate electrode is further capacitively coupled with the floating gate electrode through a composite gate insulating film structure implemented by a silicon

HOW MUCH IS THE current passing through electrodes placed on head, i also want to know in which places these electrodes are placed on head to take an EEG ?

for taking eeg it is the minutest amount of vibrations to detect you can say it is negligible...There is very minor EEg is placed on your head & for taking eeg it is the minutest amount of vibrations to detect you can say it is negligible.

What is the full form of LCD?

in battery-powered electronic devices because it uses very small amounts of electric power.Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, and two be blocked by the second crossed polarizer.The surface of the electrodes that are in contact with the liquid crystal material are treated so as to align the liquid crystal molecules in a particular direction

. Which one is a cross field tube a. Klystronb. Reflex Klystronc. Magnetrond. TWT

A third, partially transparent grid electrode is interposed between the anode and cathode and electrically tied to the cathode by a grid leak resistor. High voltage is first applied to the anode, laboratory tube and not by the physics of the technique....b. Reflex Klystron...A third, partially transparent grid electrode is interposed between the anode and cathode and electrically tied to the cathode by a

what do you mean by vacuum tubes ?

electrode the anode or plate. Two-electrode Edison-effect tubes were first employed as radio-frequency detectors, but the enormous potential of the device was not realized until it was shown that the current could be controlled with large amplification ratios and great sensitivity by small electrical charges on a third, meshlike electrode the grid interposed between cathode and anode. From the resulting three

What is a Plasma monitor?

between two plates of glass. Long electrodes are also sandwiched between the glass plates, in front of and behind the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted in front of the cell, along the front glass plate

What are tri-state devices and why they are essential in a bus oriented system?

, and an output electrically coupled to a control electrode of said normally-off transistor so that the tri-state output becomes electrically connected through the normally-off transistor to the first reference-state device, respectively, and an output electrically coupled to a control electrode of said normally-off transistor so that the tri-state output becomes electrically connected through the normally

What is TFT in TFT Monitors

-crystal image with such cells: the segment driving method and the matrix driving method.The segment driving method displays characters and pictures with cells defined by patterned electrodes.The matrix driving method displays characters and pictures in sets of dots.How TFT LCD Pixels WorkA TFT LCD panel contains a specific number of unit pixels often called subpixels.Each unit pixel has a TFT, a pixel electrode

what is a triode?

hi yatin,a thermionic vacuum tube having three electrodes; fluctuations of the charge on the grid control the flow from cathode to anode which making amplification possible...well , A triode is a type.en.wikipedia.org/wiki/Triode...A triode is an electronic amplification device having three active electrodes. The term most commonly applies to a vacuum tube or valve in British English with three elements: the filament or cathode

what is the plasma TV really?

is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long electrodes are also sandwiched between the glass plates, on both sides of the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted

What is FET

path called the channel. At one end of the channel, there is an electrode called the source. At the other end of the channel, there is an electrode called the drain. The physical diameter of the channel is fixed, but its effective electrical diameter can be varied by the application of a voltage to a control electrode called the gate. The conductivity of the FET depends, at any given instant

We can surely recycle the carbon rod positive electrode in battery cells. Is anybody/organisation listening?

Can anyone pls tell me where i can get colloidal silver setwith electrodes in delhi?? i heard it cures chronic infection like sinus and tb..?
