what are the terminals of a transistor?
231017
A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals.

A Transistor switch, which is used for opening or closing of a circuit, that means the transistor is commonly used as a switch in the electronic devices only for the low voltage applications because of its low power consumption.Transistor work as a switch when it is in cutoff and saturation regions.

The F1 terminal measures 3/16″ (0.187″) – 4.75mm wide. ... The F2 terminal measures 1/4″ (0.25″) – 6.35mm wide. F2 terminal positions are usually at the top of the battery. The F2 terminal is also known as TAB 250.

The fundamental principle behind all transistors is simple: Current flow between two terminals is prevented by an energy barrier that has been set up between them. To operate the transistor, a third terminal is provided that allows you to lower the energy barrier.

Alpha of a transistor is the current gain in common base configuration defined as the ratio of change in collector current to change in emitter current while beta is the current gain in CE configuration. It is defined as the change in collector current to base current.

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.

The alpha factor (α) of a transistor is the ratio of its collector and emitter currents (α = Ic/Ie), and it is always less than 1 (between 0.5 and 1). The beta (β) or current gain is the ratio of its collector and base currents (β = Ic/Ib), and it is always more than 1.

NPN Transistor as a Switch Based on the voltage applied at the base terminal of a transistor switching operation is performed. When a sufficient voltage (Vin > 0.7 V) is applied between the base and emitter, collector to emitter voltage is approximately equal to 0. Therefore, the transistor acts as a short circuit.

Bipolar junction transistors (Also known as BJTs) can be used as an amplifier, filter, rectifier, oscillator, or even a switch, which we cover an example in the first section. The transistor will operate as an amplifier or other linear circuit if the transistor is biased into the linear region.

Analog and Digital Circuits Most of the fundamental electronic components -- resistors, capacitors, inductors, diodes, transistors, and operational amplifiers -- are all inherently analog. ... Small changes in the voltage level of an analog signal may produce significant errors when being processed.

A MOSFET is a type of FET. It stands for "metal oxide semiconductor field effect transistor". All MOSFETs are FETs, not all FETs are MOSFETs. But the term is so common that things that are not actually MOSFETs are still called "MOSFETs", so there isn't really much difference; the terms are kind of interchangeable.

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. ... Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.

TTL (Transistor Transistor Logic) IC technology uses bipolar transistor as principal circuit element. CMOS (Complementary Metal Oxide Semiconductor) IC technology uses FET as principal circuit element. ECL (Emitter Coupled Logic) IC technology uses bipolar transistors configured as differential amplifier.

A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other.

5.2 The Bipolar Transistor - Principle of operation. A bipolar junction transistor consists of two back-to-back p-n junctions, which share a thin common region with width, wB. Contacts are made to all three regions, the two outer regions called the emitter and collector and the middle region called the base.
