Zener Diode is a special type of diode that can conduct in forward as well as in reverse bias mode. This special diode is named after American physicist Dr. Clarence Melvin Zener. We will discuss working principles that underscore its distinctive behavior— specifically, construction, Zener effect, and avalanche breakdown. The Symbol of a Zener Diode […]
In the Delta connection, the dissimilar terminals of three phase windings are connected together. The finishing end of one phase is joined to the starting end of the other phase to obtain mesh or delta-connected winding. Delta connection in the power system is shown in the below diagram As shown in the diagram of the […]
Armoured cables represent a significant advancement in the field of electrical engineering, designed to offer enhanced safety and protection in demanding industries and environments. Comprising various elements such as conductors, insulation, bedding, armour, and sheath, these power transmission linchpins are constructed with careful attention to detail to ensure optimal resilience and reliability. Understanding the anatomy […]
In this article, we will explore the basics difference between AA and AAA battery, including their size, capacity,common uses and voltage. AA and AAA batteries are two common types of household batteries. The main differences between them are their size and capacity. AAA battery is also called a Pencil cell. AA battery is bigger than […]
All electrical devices run on electrical power, the consumed energy is measured in terms of watts. the device used to measure consumed power is called a watt meter. to measure three-phase power mainly two methods are used namely two wattmeter method and three wattmeter method. In this article, we will discuss two wattmeter method of […]
The permanent magnet moving coil instruments (PMMC instrument) are suitable for DC quantity measurements only. PMMC instruments working principle based on Faraday’s law of electromagnetic induction state that when the current carrying coil is placed in the magnetic field it experiences force and torque act on the coil and it starts moving. Construction of PMMC Instrument […]
This bridge was first introduced by Wheatstone for measuring the value of unknown resistance. Wheatstone bridge circuit consists of four resistors, two with known resistances P & Q and one known variable resistance R, and one unknown resistor X whose value is to be calculated. All four resistors are connected in a manner to form a […]
When the current-carrying conductor placed in a magnetic field, it experiences a force due to the magnetic field on the other hand if the conductor moved into the magnetic field an emf gets induced across the conductor as per faraday’s law. Hence the direction of the force and the direction of induced emf current can […]
Definition: The difference between the true value and the measured value of the quantity is known as an error in measurement. The error in measurement can not be eliminated completely but it can be minimized. there are various types of errors in measurement. Calibration Errors Types of Errors in Measurement Base on the nature of […]
There are many electrical components are used in the electronic and electrical circuit like a resistor, inductor, diode, transformer, capacitor, and many more. without these electrical components, the circuit is incomplete. each part has a different function in the circuit. so they are the most important components of the circuit. all these basic electrical components […]
