contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. Adding one or more control grids within the tube allows the current between the cathode and anode to be controlled by the voltage on the grids.[5]

∙ 9y agoVacuum tubes mostly rely on thermionic emission of electrons from a hot filament. The harder the vacuum, the better the tube will work and the longer it will last.

Mine is simple, Kinda like a vacuum, But is a tube!

How many vacuum tube in one transistor?
There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.
What is the difference between vacuum tubes and transistors?
A vacuum tube is a current amplifier where the transistor amplifies voltageA tube is a voltage amplifier. A transistor is a current amplifier. A tube is an older design that requires substantial voltage to operate correctly. A transistor is a semiconductor device that operates on relatively low voltage.
Can you measure a vacuum tube using ohmmeter?
Maybe, but not sure info would be useful. You can use ohmmeter to check that a tube's filament is intact. Broken/burned-out filament is most likely reason for dead tube.
How can you replace transistor with vacuum tube?
A: ABSOLUTELY but only in its function . To implement a change requires additional power requirements and design
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
What computer component did the transistor replace?
the vacuum tube
What does it tell you about a vacuum tube if you see the getter of that vacuum tube is no longer silvery but has turned white?
It means that the glass envelope has leaked and is no longer a vacuum. Air inside has oxidized the getter. They generally no longer work in this condition.
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
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.
How many KB is a vacuum tube?
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
How exactly does a vacuum coffee maker work?
A vacuum coffee maker sucks water using a vacuum tube through a filter with coffee grounds in it, making the water quickly turn into a rich flaavorful coffee.
What are example of vacuum tube?
cellphone
What does the first generation vacuum tube look like?
* == 1st generation vacuum tube look like as a parallel electric bulb. _____ ----_____)
