How does Transistor Work

 The transistor is a semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits that containing billions of minuscule devices etched into the surface. It is used as an amplifier or switches electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. the word transistor is made of the two words, transfer and resistance. This is because it has the function of transferring the resistance from one end of the device to the other end or we can say, transfer of resistance. Transistors have very high input resistance and very low output resistance. 




It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. It works when the holes start moving across the two junctions between the n-type and p-type silicon. When turning a small input current into a large output current, the transistor acts as an amplifier. But it also acts as a switch at the same time when this happens.

A transistor consists of two diodes connected back to back. It has three terminals namely emitter, base, and collector. The basic idea behind a transistor is that it lets you control the flow of current through one channel of a much smaller current that's flowing through a second channel. 

There are two types of transistors. One is BJT and the other is FET.

The primary transistor is the BJT and get is the modern version of the transistor. The types of BJT are NPN and PNP transistors. In an NPN transistor, a positive voltage is given to the collector terminal to produce a current flow from the collector to the emitter. In a PNP transistor, a positive voltage is given to the emitter terminal to produce current flow from the emitter to the collector. The FET is quite an unknown device in this modern time. The device means that it is made using either p-type or n-type material as the main substrate. 

Transistors are used in our day-to-day lives in many forms. As amplifiers, they are being used in various detectors, and nearly in any circuit in order to perform a function. In digital circuits, transistors are used as switches. Transistors make excellent electronic switches. They can turn currents on and off super fast. Digital computers use transistors as a basic mechanism for storing and moving data. 

Transistors are also found in hearing aids, cameras, calculators, and watches. most of these devices draw their power from tiny batteries. most spacecraft also rely on microchips, and thus transistors. The transistor is called the nerve cell of the information age.

The Causes of Load Shedding

 Load shedding is a terrible thing to experience. Especially in summer. But have we ever wondered what causes load shedding? Load shedding is the shutdown of the power distribution system when the capacity of power is less than the demand. Today we will discuss this topic briefly.  Load Shedding Load shedding is an intentional blackout in engineer electrical power shutdown for a time period in different parts of the distribution region. Load shedding depends on the shortage of capacity to meet the demand for electricity. load shedding occurs to avoid a complete blackout of the power system. Blackouts can be localized to a specific part of it can be in the whole country. Sometimes blackouts can happen due to extreme weather. Usually, the blackouts can be caused by insufficient capacity or inadequate infrastructure to deliver power.  The causes of load shedding 1. System loss After producing the power the next part is to distribute it among the consumers. But if the suppli...

5 Ways How Artificial Intelligence Will Impact Our Future

In the world of technology AI is on the tip of everyone's tongue these days. AI being a major trend in tech development for a while, AI appearing more and more like one of the most demands in areas of expertise. Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. Specific applications of AI include expert systems, natural language processing, speech recognition, and machine vision. Most artificial intelligence systems have the ability to learn, which allows improving their performance over time. The recent research on AI tools, including machine learning, deep learning, and predictive analysis intended toward increasing the planning, learning, reasoning, thinking, and action-taking ability. As AI is becoming part of our life, it will affect our future nearly. Here I am showing some of the scenarios that can be happen in near future: Transportation: Although it could take a decade or more to happen, autonomous cars will...

What Does It Mean By Dny11 in Transformer?

We often see transformers in our way almost every day, everywhere. We all might have noticed that there is something written in the transformer like Dny11. But we don't know what does it mean? We can guess that the numbers on the transformer windings show the turns ratio between windings. But by reading this article we might confirm this guess.  The first letter D shows that the primary winding configuration is in delta connection. The second small letter n shows that it has the neutral point and the small y shows that it is star connected. Letter 11 shows the phase difference between the primary and secondary connection according to clock configuration. When the clock hands are between 11 and 12 the angle between them is 30 degrees. So, Dny11 means  D- Primary winding in delta connection ny-Secondary winding in star connection with a neutral point 11- There is a phase angle difference of 30 degrees between the primary and secondary line voltages. The secondary line voltage la...
