Basically it looks (and is, somewhat) like a stretched out light bulb.
At the front you have the square flatened surface where the picture is displayed, behind it you have a stem, sort of like the stem of a light bulb.
At the end of the stem you have a filament like the one a bulb has and that send electrons towards the front.
Around that glass stem, still at the back, there are some coils which deflect the beam OS electrons to render the picture on the phosphor at the front. Those look like some noodles made of copper wire.

What are computer tubes used for?
Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.
Advantages and disadvantages of vacuum tube?
Vacuum tubes have superior sound quality and are typically easy for the user to replace on their own. Disadvantages include their size, rather large for portable devices, and they generally use a larger amount of power then transistors.
When was the 1st amplifier made?
the first amplifier was made in the year 1909. this was the audio amplifier of vacuum tube type.
What does cathode ray tube mean?
A cathode ray tube is what was used in televisions and computer monitors before the advent of the LCD, LED, and Plasma tv screens. They are big, bulky, and very heavy. They are a vacuum tube, with an approximately flat face, on the inner surface of which is deposited a phosphor. When electrons from the cathode asembly reach the phosphor, they cause it to glow at that spot.
Is a vacuum an absence of electricity?
No, a vacuum is an absence of matter.
What does the first generation vacuum tube look like?
* == 1st generation vacuum tube look like as a parallel electric bulb. _____ ----_____)
What computer component did the transistor replace?
the vacuum tube
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 does the esophagus look like?
The esophagus is referred to as your "food tube" so it is like cylinder.it is a tubular shape
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 a vacuum on a 1992 Chevy S-10 look like?
You can't see a vacuum, a vacuum is a process.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
Do vacuum tubes in computers burn out like light bulbs?
Yes, vacuum tubes in computers burn out. Transistors are much better. Vacuum tube computers no longer exist except in museums. Vacuum tube computers were originally made in World War 2 to calculate the positioning of antiaircraft guns. It was not necessary to know where the airplane was but where it would be when the explosive arrived. That was especially true when the Germans developed the buzz bomb going 450 miles an hour. When hundreds of transistors could fit in the same area as one vacuum tube, the vacuum tube vanished.
