There is a category of transistors called Field Effect Transistor (FET). In this category, a lot of field effect transistors are there like Junction Field Effect Transistor (JFET), Metal Oxide Field Effect Transistor (MOSFET), Metal Semiconductor Field Effect Transistor (MSFET), etc. In this article, we will compare and contrast the various features of JFET and MOSFET.What is JFET?JFET stands for junction field effect transistor. The JFET is a three terminal semiconductor device and the terminals are: Source (S), Drain (D) and Gate (G). JFET has a channel between source and drain. The channel is the path between the source and ... Read More
A motor in general is an electrical machine that converts electrical energy into mechanical energy. Electric motors can either be DC Motors or AC Motors, depending on the type of power supply that is supplied as its input.AC motors are further classified into two types−Asynchronous or Induction MotorSynchronous MotorA synchronous motor always runs at synchronous speed, while an induction motor runs at a speed less than the synchronous speed.Read through this article to find out more about synchronous motors and induction motors and how they are different from each other.What is a Synchronous Motor?A synchronous motor is a type of ...

An electrical transformer is tested at the transformer manufacturer premises and at the consumer’s site and also periodically in regular and emergency basis during its service life to confirm its specifications and performance.Types of Transformer TestsTests of transformer done at the manufacturer’s premises −Type testsRoutine testsSpecial testsTests of transformer done at the consumer’s site −Pre-commissioning testsPeriodic testsEmergency testsType Tests of TransformerThe type tests of a transformer are performed at the manufacturer’s premises to prove the design expectations and consumer’s specifications. The type tests are performed in a prototype unit, not in all manufactured units and these tests confirm the basic ... Read More
A computer instruction is a binary code that determines the micro-operations in a sequence for a computer. They are saved in the memory along with the information. Each computer has its specific group of instructions.They can be categorized into two elements as Operation codes (Opcodes) and Address. Opcodes specify the operation for specific instructions. An address determines the registers or the areas that can be used for that operation. Operands are definite elements of computer instruction that show what information is to be operated on.It consists of 12 bits of memory that are required to define the address as the ... Read More
In an AC electric circuit, when the capacitive reactance is balanced by the inductive reactance at some given frequency, then this condition in the circuit is referred as resonance. The frequency of the supply voltage at which resonance occurs in the circuit is called resonant frequency. At the resonance in the circuit, the reactance of the capacitor and inductor cancel each other. Also, at the condition of resonance, no reactive power is taken from the source.Based on the arrangement of capacitor and inductor in the electric circuit, the resonance is divided in two types viz. −Series resonanceParallel resonanceIn this article, we ...

When the transformer is in operation, heat is generated due to copper losses in the windings and iron losses in the core. The removal of heat from the transformer is known as cooling of the transformer.Transformer Cooling MethodsFor the dry type transformersAir Natural (AN) CoolingAir Forced (AF) or Air Blast (AB) CoolingFor oil immersed type transformersOil Natural Air Natural (ONAN) CoolingOil Natural Air Forced (ONAF) CoolingOil Forced Air Forced (OFAF) CoolingOil Forced Water Forced (OFWF) CoolingAir Natural (AN) CoolingThe air natural (AN) cooling is used in dry type, self-cooled transformers. In this method, the natural circulation of surrounding air is ... Read More
Linked List The linked list is a linear data structure containing elements called nodes. Each node consists of two main components: data (payload of that node) and a pointer to the next node in the list. They are simple and efficient to use providing easy allocation and deallocation of memory. Doubly Linked List Doubly linked list is a special type of linked list which again consists of a basic element called nodes. Each node consists of three main components: data (payload of that node), a pointer to the previous node of the sequence and a pointer to the next ... Read More
In today’s world with a large amount of data and interconnected systems, a vast amount of data is created and stored across various machines. One challenging challenge is to sort this data stored across multiple devices. Sorting being a fundamental operation in computations is used for optimal retrieval, search and analysis of data. But with distributed systems and various interconnected machines, this task of sorting becomes difficult and important. Problem Statement Given an array containing N linked lists that depict N different machines. Each of these linked lists contains some variable number of numbers in sorted order. The task is ...
