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.
Vacuum tube was invented by lee de forest .
1904, a diode by Fleming.
John Ambrose Fleming invented the vacuum tube in 1904.
Vacuum tubes were invented by Thomas Edison in the 1880s. However, it was later improved by Lee De Forest in the early 20th century, who added a grid electrode and introduced the concept of the triode vacuum tube.
The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.
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.
