Transistors A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: 1  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.2  Transistors can also work as switches.ormally, the holes in the base act like a barrier, preventing any significant current flow from the emitter to the collector while the transistor is in its off state. A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon.

How to Connect a Transistor in a Circuit for Current Amplification How to Connect a Transistor in a Circuit for Current Amplification. In this circuit, we will show how to connect a transistor in a circuit for current amplification. Transistors are devices that can amplify a signal in a circuit. If a signal in a circuit is too weak, it may not be enough to provide power to turn or or drive the load for a circuit.

How Semiconductors Work Semiconductors have had a monumental impact on our society. You find semiconductors at the heart of microprocessor chips as well as transistors. Anything that's computerized or uses radio waves depends on semiconductors.Today, most semiconductor chips and transistors are created with silicon.

What is the function of transistors in a computer? As integrated circuits are developed, the size of each transistor gets smaller, so more can be packed into single chips but they are still doing the same job as the individual transistors that were used to build the very first solid state computers.

Computer Hardware (See: wikipedia chip) Note that silicon (chips, solar panels) and silicone (soft rubbery material) are different! The most common electronic component is the transistor which works as a sort of amplifying valve for a flow of electrons. The transistor is a solid state device, meaning it has no moving parts.

What does a transistor do and how does it work? Rating Newest Oldest. Best Answer: There are at least two types, FET (Field Effect) and BJT (Bi Junction). I'll kind of mash up the two in the explanation. A transistor has three connections. There is one connection that is a current source, one that acts as a gate, and another where the current leaves.As a small signal is provided at the gate, a larger current passes through the transistor.This allows it to provide amplification.ating Newest Oldest.

- You will usethe MOSFET as a variable resistor and as a switch.BACKGROUNDThe MOS (metal-oxide-semiconductor) transistor (or MOSFET) is the basic building blockof most computer chips, as well as of chips that include analog and digital circuits. In this lab,we will work with what is called an n-channel MOS transistor. The internal structure andoperation of this device, as well as of its complement, the p-channel MOSFET are studied insemiconductor device courses.

After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality.

What Is a Transistor? Answer: At its core, a transistor is an electronic component used in a circuit to control a large amount of current or voltage with a small amount of voltage or current.It does so by sandwiching one semiconductor between two other semiconductors.ost. Share. There are essentially two basic types of point-contact transistors, the npn transistor and the pnp transistor, where the n and p stand for negative and positive, respectively. The only difference between the two is the arrangement of bias voltages.

Electronics Components: Look inside a Transistor Collector-emitter: The main current that flows through the transistor. Voltage placed across the collector and emitter is often referred to as V ce, and current flowing through the collector-emitter path is called I ce. Base-emitter: The current path that controls the flow of current through the collector-emitter path.n a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides. Most circuits that you can build with an NPN transistor can also be built with a PNP transistor. But if you do, you must remember to flip the power connections.

- A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.It is composed of semiconductor material with at least three terminals for connection to an external circuit.ollector current is approximately β (common-emitter current gain) times the base current. It is typically greater than 100 for small-signal transistors but can be smaller in transistors designed for high-power applications. Unlike the field-effect transistor (see below), the BJT is a low–input-impedance device.

Transistor as a Switch Here the transistor will be biased so that the maximum amount of base current is applied, resulting in maximum collector current resulting in the minimum collector emitter voltage drop which results in the depletion layer being as small as possible and maximum current flowing through the transistor.

How Transistors Work EyesWideOpen/Getty Images. Transistors are devices that control the movement of electrons, and consequently, electricity. They work something like a water faucet -- not only do they start and stop the flow of a current, but they also control the amount of the current. With electricity, transistors can both switch or amplify electronic signals, letting you control current moving through a circuit board with precision.

Lessons In Electric Circuits -- Volume III 1 A Silicon-Controlled Rectifier, or SCR, is essentially a Shockley diode with an extra terminal added. 2  This extra terminal is called the gate, and it is used to trigger the device into conduction (latch it) by the application of a small voltage.nijunction transistor: Although a unijunction transistor is not a thyristor, this device can trigger larger thyristors with a pulse at base B1. A unijunction transistor is composed of a bar of N-type silicon having a P-type connection in the middle.

- A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.It is composed of semiconductor material with at least three terminals for connection to an external circuit.he transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current.
