In this system, a delta/star-connected transformer is used. Three wires are taken from the phases and the fourth wire (i.e. neutral wire) is taken from the star point. If the voltage of each phase conductor to neutral is V then line to line voltage between the phases will be √3V. The 3 phase 4 wire […]
Hi friends, In this article, I am discussing the moving coil galvanometer working principle, its construction and conversion into voltmeter and ammeter. So let us start our topic. A moving coil galvanometer is an easy and sensitive instrument to detect and measure electric current. Galvanometer Working Principle The working principle of galvanometer is based upon the
The Kirchhoff’s Laws are very useful in solving electrical networks which may not be easily solved by Ohm’s Law. In this article, I will describe these laws and will show some of Kirchhoff’s voltage law examples to make these laws easily understandable. Kirchhoff’s Laws, two in number, are as follows: Kirchhoff’s Current Law: This law
Hi friends, in this article, I am going to explain the electroplating process steps and hope you will find it very informative and interesting. The electroplating is an art of depositing a superior or more noble metal on a base metal by means of electrolysis. For example, metals like iron are coated with deposits of nickel or
A transistor can also act as a switch and can turn ON and OFF power in an electrical load. The action of the transistor, while using a transistor as a switch is explained below: Switching Action of a Transistor To understand the switching action of a transistor in detail, consider the collector characteristics for a
Hi friends, in this article, I am going to describe the linear induction motor working principle. This article will provide you answers of various questions about the LIM. A linear induction motor is a developed version of cylindrical induction motor. It is special type of induction motor which gives linear motion instead of rotational motion
Hi friends, In this article, I am discussing the “working of stepper motor“. This article will definitely increase your knowledge about stepper motors, I hope so. The stepper motors convert electrical pulses received by their excitation (control) winding into discrete angular displacements-commonly called as steps. The characteristic property of the stepper motor is the step-by-step turning of the
Hi friends, In this article I am discussing the OTEC working principle, types, advantages and disadvantages. You will find this article informative and interesting, I hope so. The oceans and rivers cover about 70% of the earth’s surface which receives, store and dissipates the vast amount of thermal energy. Thus they act as
Geothermal Power Plant Working Principle The geothermal energy in the form of heat energy can be used to generate electricity economically and efficiently. It is a renewable source of energy and is inexhaustible like solar or wind energy. Though the amount of thermal energy within the earth is very large, useful resources of geothermal energy are
Hi friends, in this article I am going to discuss about solar panel working principle and hope you will like my effort. In the solar photovoltaic system, solar energy is directly converted to electric power. This makes the system far more convenient and compact compared to thermal methods of solar energy conversion. The solar cell technology is
