The main disadvantage of vacuum tubes is that they require bulky power supplies. As there is high voltage electric shock hazard is also there.

∙ 15y agoIn the western world they have been obsolete since the mid sixties, creating supply problems. They are heavy and generate possibly unwanted heat-but this can be and is tamed by heat sinks and exchangers. They require on the average eleven seconds to warm up as opposed to(Instant on) Transistors. They are all things being equal more bulky than solid state devices and can only be miniaturized so much, still they have their advocates and fans.

Why modern devices use integrated circuit instead of vacuum tubes?
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
What theorem is used in vacuum tubes?
Millman's theorem
What network theorem is generally used in the analysis of vacuum tubes?
Millman's theorem
Why many modern electronic devices use integrated circuits instead of vacuum tubes?
Integrated circuits consume less power, are smaller, can be more complex in a much smaller space and are cheaper to make for similar functions than vacuum tubes.
What are the benefits of 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.=]
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
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.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
Where is a good place near Seattle where you can buy old 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
Where was vacuum tube was made?
who made the vacuum tubes
How many vacuum tubes in first generation computer?
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
Why modern devices use integrated circuit instead of vacuum tubes?
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
Vacuum tubes generation?
first
What has the author Karl R Spangenberg written?
Karl R. Spangenberg has written: 'Vacuum tubes' -- subject(s): Vacuum-tubes
Do vacuum tubes did it lead to an increase or decrease in size?
Vacuum tubes vary from thumb size to larger than most people. Integrated circuits or ICs' are the size of you little finger nail. There was nothing worth remembering before vacuum tubes.
