What was the first diode discovered referred to as?
The first diode discovered is referred to as the "vacuum tube diode," or simply the "diode." It was invented by John Ambrose Fleming in 1904 and consists of a heated cathode and an anode in a vacuum, allowing current to flow in one direction. This invention laid the groundwork for the development of modern electronics.
When were filament tubes invented?
The first hot filament diode tube was invented in 1904 by Fleming, the first hot filament triode tube was invented in 1907 by DeForest. However it was not until 1913 that it was determined that high vacuum was actually needed for efficient and reliable operation of these tubes. So true hot filament vacuum tubes were not made and used until 1913.
What is the advantage of triode?
With a diode tube you have no control over the current flow and it can only be used as a rectifier, where the triode consist of a control grid, to control the flow of electrons that will reach the anode, this make it possible to use the triode as a amplifier, compared to a transistor the control grid have the same function as the base of the transistor.Advantages?Over tetrodes and pentodes:1. Operation at higher radio frequencies,2. Lower noise figures,3. Simpler circuitry and only one power supply.
Who invented the first solid state diode?
A diode is an electronic component with two terminals that conduct asymmetrically. Although there are different types of diodes with different invention histories, the thermionic diodes were first described by Frederick Guthrie in 1873.

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.
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".
When were the vacuum tubes invented?
1904, a diode by Fleming.
Who invented diode and when?
The first diode was the Galena Cats Whisker. It was invented shortly after the development of radio, but I'm not sure by who.Fleming's vacuum tube diode came shortly afterwards.
Who is the inventor of vacuum tubes?
Sir John Ambrose Fleming patented the thermionic diode in 1904. Then Lee DeForest put a control grid into it to create the triode in 1906.
Who and when the invention of vacuum tubes?
In connection with his work on the electric light, Thomas Edison played with a vacuum diode,which he made by adding a plate electrode to one of his incandescent bulbs. It was definitelya vacuum tube, but all it could do was rectify, which was certainly a valuable talent, but hadlimited usefullness.Dr. Lee DeForest added the grid electrode to Edison's diode, creating a triode with the ability topower-amplify small signals, and to create self-sustaining oscillation. I think that was in 1907.
Why a triode cannot be used as a rectifier?
Actually it can be used as a diode, but rarely is. Just connect the grid and plate together and it has been reduced to a diode. There are also certain circuits that use the cathode and grid as a diode, while also obtaining an amplified output on the plate.
When were filament tubes invented?
The first hot filament diode tube was invented in 1904 by Fleming, the first hot filament triode tube was invented in 1907 by DeForest.

Which diode has its characteristics very close to that of an ideal voltagesource.1.zener diode 2.vacuum tube diode 3. crystal diode?
The Zener diode has the characteristics of a constant voltage source.
Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
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.
