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.

What is the solid state diode?
A solid-state diode is a diode where the electrons flow through only solid materials. Nearly all diodes in common use are solid-state.
How do you identify the polarity of a diode when the tester is on diode scale?
To my own understanding, you will use multi-meter to test for the polarity
What is the negative leg of an LED called?
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
Is led a voltage controller or current controller?
An LED is a diode that emits light; diodes allow current to flow only one direction. The voltage applied to the diode attempts to force current to flow in a specific direction. If the voltage polarity is reversed, and current was flowing before (so there was a small voltage drop across the diode), current will cease to flow (assuming the voltage is not too high for the diode to handle), and (almost) all the voltage will be dropped across the diode (a small leakage current may flow, which means some of the voltage will not be dropped across the diode, but this is in the milli or micro range). I would never define a diode as a "voltage controller" or "current controller". It could be either or both, from the above description.
Which mode is use in digital multimeter for testing of diode?
A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.

What is an electronic vacuum valve with three electrodes?
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".
What is diode volve?
I think you mean 'diode valve'! A 'valve' is the British term for what Americans call 'tubes' or, more accurately, 'vacuum tubes'. So, a 'diode valve' is a thermionic valve generally used as a rectifier, much in the same way that a semiconducting diode is used, these days.
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.
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 does BY stand for in BY 127 diode?
BIPOLAR A2 It does not stand for anything. It is a maker's designation mark, a throwback from the thermionic tube (valve) days. The letters in front of the number used to indicate the heater voltage and the type of internals (triode, pentode etc) B used to indicate that it was a semiconductor, not a tube. There are different designations around the world, for the same equivalent device, American, European and Japanese.

What is the direction of current flow in a diode valve?
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
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 the operations of a triode valve?
Within some operating range, plate current is linearly related to grid voltage.
