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.
The saturation condition of a triode occurs when the plate is at high voltage values and the grid with respect to the cathode is?
Highly positive
Which is stronger 18 gauge steel or 22 gauge?
18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.
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.
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
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.
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".
Who invented the triode?
In 1906 Lee De Forest, an American engineer (often called the "father of radio"), invented the three-element vacuum tube, or triode.
What is an electronic vacuum valve with three electrodes?
Triode
The grid in a high-vacuum triode is usually kept?
negative
Is a triode a light bulb?
No. A light bulb is a directly-heated monode.
What do you mean by amplification factor of a triode valve?
"Triode valve" does not make sense. Please restate the question.Umm... yes, it *does* make sense.Triode "valve" is non-U.S. English for Triode tube.OK.Amplification factor is the amount of anode voltage change to give a chosen amount of anode current change, compared to the amount of grid voltage change for the same anode current change.The symbol is u (it's actually the Greek character for m), and it's called "mu".That is, using "d" for "amount of change":dVa/dVg for equal dIa.Typical values are as low as 2 (6AS7/6080 regulator valve) to 12 (6C4/12AU7 medium-mu triode) to around 100 (6AV6 high-mu triode).Some special microwave triode have mu values in the 300s.

What is the full form of TRIAC?
TRIAC is the word derrived from the 2 words TRIode and AC.
