Who invented the vaccum tube?
The vacuum tube was invented by Thomas Edison in the late 19th century. However, it was not until Lee de Forest's modification in 1906 that the vacuum tube became an essential component in early electronics.
What replaced the vacuum tube?
The transistor replaced the vacuum tube as the primary component in electronic devices, offering smaller size, lower power consumption, and higher reliability. This transition marked the beginning of the semiconductor era in electronics.
When was the vacuum tube invented?
The vacuum tube was invented in 1904 by John Ambrose Fleming, an English engineer.
Who made the beam of electrons in vacuum tube?
J.J. Thomson is credited with creating the first beam of electrons in a vacuum tube in the late 19th century. This discovery led to the development of the cathode ray tube, which was integral to the development of television and other electronic displays.
Why is a vacuum needed in the deflection tube?
A vacuum is needed in the deflection tube to prevent the interference of air molecules with the movement of electrons. Air molecules can scatter and absorb electrons, affecting the accuracy of the electron beam's deflection. By removing air and creating a vacuum, the path of the electrons remains unobstructed, allowing for precise control and movement within the tube.
What computer component did the transistor replace?
the vacuum tube

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
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
Where was vacuum tube was made?

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.
What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
What are example of vacuum tube?
cellphone
