If by triode, you mean "a three-electrode tube", then yes.
You need a source of current into the device, a control electrode, and an "outlet" for the controlled current.
Although there were radically different types of construction, all early amplifying tubes were triodes of some kind.

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 the name of the tube used in class A amplifier with the function of dual triode developed in USA and published in September 15 1947?
There are two names for the tube used in Class A amplifiers developed in the USA. This valve in the US is called vacuum tube audio amplifier. In the UK they are known as valve audio amplifiers.
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.
How many transistors can fit in a microchip the size of a penny?
That depends:simple passive circuits have no transistorsvacuum tube circuits have no transistorssolid state circuits can have anywhere from no transistors (just diodes and/or magnetic amplifying transformers) to as many transistors as needed to perform the function
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Who was the inventor of the vacuum tubes?
Lee de Forest was the inventor of the first electronic amplifying tube, the triode. His understanding of how his invention worked was far from correct, but nevertheless he had invented the first electronic valve. Rectifying tubes had been invented earlier by J A Fleming, and it was these that de Forest improved upon - magnificently.
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
What is an audion tube?
An audion tube is an electric amplifier device invented in 1906, as the forerunner of the triode.
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.
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.
A two cavity klystron tube is a?
a. velocity modulated tube b. frequency modulated tube c. Amplitude modulated tube d. simple 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".
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.
What is an audion?
An audion was an early variety of electronic amplifying tube consisting of a partially evacuated glass tube with three electrodes, a heated filament, a grid and a plate.
Explain briefly about field effect transistor?
Think of a solid state triode vacuum tube, the mathematical model is almost identical.
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.
What is a TRIODE and what are its uses?
A triode is a vacuum-tube (US) aka valve(UK) with three electrodes : an anode, a cathode and a grid. The cathode is heated electrically which boils off a cloud of electrons. The anode is made positive ( typ. 100-500V) which attracts the electrons towards it. The grid is an open structure, usually of thin wires, placed between the anode and cathode, but nearer the cathode. If a negative voltage is applied to the grid the current flow through the tube is reduced. The more negative, the less current. Prior to the development of transistors, tubes were used for all things in radio,TV and electronics. Different tubes had different numbers of electrodes; the triode was particularly suited to high power amplifiers, especially at radio frequencies. Triodes are still used today by shortwave radio stations, and for RF heating equipment.
