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.

Who invented the bandaid and when was it invented?
The bandaid was invented in 1921 by Earle Dickson.
Who invented the genatles?
14 billion years invented the genatles then, in turn, they invented you.
What is a crystal triode?
A crystal triode is the old term for transistor. Crystal diodes were well established by the time transistors were invented, so using vacuum tube terminology, the logical name for a diode whose current could be controlled by a third element was "crystal triode".
What is an audion tube?
An audion tube is an electric amplifier device invented in 1906, as the forerunner of the triode.
What was a weakness of Thomas Edison?
Thomas Edison tended to hold on to a particular idea too long. As a result Edison held on to the idea of using direct current instead of alternating current much too long. Edison invented the diode. When the triode was invented Edison continued to try to accomplish with the diode what the triode accomplished easily. His weakness was he did not see when an idea should be dropped.
What is an equivalent diode of a triode valve?
Hard to answer this one.The triode is a diode with a control electrode (the grid) added.The only useful answer is that a triode is a voltage-controlled doide.Try asking the question so that it can be answered more usefully.
Why you use tetrode instead of triode?
a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.OK, but the question was "why use a tetrode instead of a triode?"So, the answer...1. A tetrode has a higher voltage/power gain than a triode.2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.
How a triode works as basic amplifier?
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
Can be a triode tube PET 25W be damage due to electric fluctuation?
Can a triode tube PET 25W be damaged due to electric fluctuation
First electronic device?
relay and vacuum tube are the electronics devices which are invented firstly in the field of electronics. but they are not revolutionary as transistor which was discovered by John Bardeen.after that other devices are invented like fet mosfet and after that digital devices was invented with the help of these devices.
What is an electronic vacuum valve with three electrodes?
Triode
The grid in a high-vacuum triode is usually kept?
negative
What are the function of vacuum tubes?
The earliest vacuum tubes were used as direct display devices, and also as rectifiers of alternating current. In 1906 Lee De Forest invented the triode valve, from which all subsequent vacuum devices have devolved. The triode allowed the electronic amplification of electrical signals, and from this, our modern communications industries have developed. Amplifiers may be made into oscillators by applying feedback. The triode may also be made into a switch (of various sorts), and this is the base on which the digital industries are based. This craft embodies the technologies of electronics, combined with Boolean algebra and signal theory. Quite complex assemblies of valves may be combined, such as triode-hexode combinations. Very large power may be controlled by the triode principles. Modern Thyristor assemblies - today's solid-state equivalent of the vacuum tube - may be used to control Megawatts of power in High Voltage Direct Current transmission systems.
Is a triode a light bulb?
No. A light bulb is a directly-heated monode.
