What are the role of cathode tubes in atom?
cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.
What were the two main problems of using vacuum tubes in computers?
Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.
Do LCD TVs use cathode ray tubes?
Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes. When newer designs (e.g. plasma, LCD, LED) came out that naturally produced flat screens and were lighter weight than cathode ray tubes, they rapidly made flat screen cathode ray tube TVs obsolete.
What is a sentence with the word transistor in it?
A transistor is a solid state electronic device that replaced vacuum tubes for most uses.
Why transistor is so necessary?
Without the transistor you would need vacuum tubes to accomplish the same thing. None of our inexpensive portable electronics would be possible using 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 came after the transistor radio?
The scientists that were responsible for this invention was John Bardeen, Walter Brattain, and William Shockley. Bardeen, with a Ph.D. in mathematics and physics from Princeton University, was a specialist in the electron conducting properties of semiconductors.

What household objects have a vacuum in?
the cathode ray tube in an older TV or monitor. valves (vacuum tubes) in older radios or stereos. some stereos and record players are still made with for those who wish. Fluorescent tubes and incandescent bulbs are made with a low pressure not quite a vacuum.
Do plasma T.V's use cathode ray tubes?
No
What components has the transistor replaced?
Mainly vacuum tubes.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
Who was the transistor invented for?
The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.
How do scientists detect cathode rays?
Cathode rays are found in vacuum tubes. Scientists are able to view them when they are a negative cathode because they emit a light and can glow.
