A closed vessel having electrodes at either end and containing agas at low pressure. When a sufficient voltage is applied to theelectrodes, an electric current flows through the gas. Dischargetubes can be used to prevent current flow below a certainvoltage; they can also function as lamps by the use of ionizinggas, which glows when current flows through the tube.

How discharge tube is different from tube light?
discharge tube can be used for indentifying electrons while tube light cxannot
What replaced the vacuum tube?
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
Is vacuum tube ohmic or non-ohmic and why?
Vacuum tubes are non-ohmic devices
Can sound travel through vacuum tube?
Sound cannot travel through vacuum, but unless there is sufficient insulation, sound might travel through the material the tube is made of.
Why must there be a near vacuum in the tube of mercury barometer?
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
What noble gas is orange?
Neon glows reddish-orange in a vacuum discharge tube
What noble gases is red?
Neon glows reddish-orange in a vacuum discharge tube
What computer component did the transistor replace?
the vacuum tube
How discharge tube is different from tube light?

What gas is used in a vacuum tube?
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What is in a vacuum tube?
Millman's theorem
Why crook tube is called discharge tube?
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
What did William Crookes discover?
Sir William Crookes was a British chemist who contributed to the knowledge of chemistry. One thing he did was discover an element that had a bright green emission line in its spectrum. He named the previously unknown element thallium.
In the Thomson experiment to determine the Specific charge of an electron If the pressure in the discharge tube is made is made as low as nearly zero dose conduction takes place?
In Thomson's experiment the tube used is evacuated i.e. there is vacuum inside.
Where was vacuum tube was made?
who made the vacuum tubes
What replaced the vacuum tube?
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
