Vacuum tubes were invented on November 16, 1904. The inventor was British engineer, John Ambrose Fleming. He died in 1945 at the ripe old age of 90.
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.
Vacuum tubes are electronic devices that control the flow of electrons in a vacuum. They were widely used in early computer and radio technology before being replaced by transistors. Vacuum tubes can amplify signals and are known for their warm, vintage sound in audio equipment.
Vacuum tubes were largely replaced by transistors. Transistors are smaller, more reliable, and generate less heat compared to vacuum tubes. This transition led to the development of smaller and more efficient electronic devices.
Vacuum electronics is the branch of electricity that deals with the behavior and motion of electrons in a vacuum or special materials, typically focusing on applications like vacuum tubes, cathode ray tubes, and traveling wave tubes. The study of electron behavior in these conditions is important for various high-power and high-frequency electronic applications.
Vacuum tubes are non-ohmic devices because their resistance changes with voltage and current. This non-linearity in resistance is due to the nature of the electron flow within the vacuum tube, causing it to exhibit non-ohmic behavior.

John Ambrose Fleming invented the vacuum tube in 1904.
The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.
Although the discovery was made of the principles for the vacuum tube around 1873 it was not put into practice until the early 1900's.
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.
It used 5200 vacuum tubes.
vacuum tubes help us today with many things. the most important 1 is techology. If we didn't have vacuum tubes we wouldn't have computers. just thik of a life with out computers or t.v. vacuum tubes are also used in radios. so if vacuum tubes hadn't been invented we would not be able to use all the techology we use today.=]
No, there are some cold cathode vacuum tubes. These do not light.
who made the vacuum tubes
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
