The Plumbicon (trademark of Phillips)is an imaging tube, think of it as the active part of a camera.
the vacuum tube
when the vacuum sucks up things it goes through the tube and into the bag ...Unless you are talking about electronics, then a vacuum tube is used to form an amplifying circuit. Some tubes can emit cathode rays onto a screen (Cathode Ray Tube = CRT) to display a picture and some can function as diodes to regulate current flow.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
Millman's theorem
A: ABSOLUTELY but only in its function . To implement a change requires additional power requirements and design
Vacuum tubes perform their various functions on the principle of streaming electrons: that is electrons able to fly across space from one electrode to another. If there is air in the tube then this is a barrier to the electron's flight and the tube cannot function.
who made the vacuum tubes
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.
The ECC83 vacuum tube is more commonly sold as the 12AX7 and is a triode tube. This tube is used in a similar way that a modern transistor would be used in audio amplification applications. The ECC83 has a smaller size and a high gain at lower signal levels making it perfect for an audio pre-amp.
an electron tube containing a near-vacuum that allows the free passage of electric current.
A Transistor is an electronic device which amplifies electrical signals, or acts as a switch. Most of the research on Transistors was performed by Shockley in 1947. That was when, the advantages of the solid state device similar in function to a Triode Vacuum tube were understood and implemented. The basic advantage was compactness..
