Dear padai

Today we are going to talk about AC generator and how AC generator works. You must have seen that there is an AC generator in many places. Mostly it is seen in big institutes, offices and weddings or even other programs. After all, why AC generator is found everywhere and why it is needed. Does it produce electricity or transfer electricity ? If it produces electricity, how does it do that? And how much electricity can it produce at one time? And what electrical appliances can it run?  AC Generator is a device used to generate a sinusoidally varying emf.  AC Generator is a device that converts mechanical energy into electrical energy producing an alternating emf.  The input of an AC generator is mechanical energy supplied by steam turbines, gas turbines and combustion engines. The output is alternating electrical power in the form of alternating voltage and current. AC Generator induces an EMF or Current in a loop through the change in its Orientation or a change in...

You all must have seen a transformer in your area and you must have seen a transformer in many places. You must be wondering why transformers are installed in every area. Does the transformer make any electricity or is it installed like this? Nor does it generate electricity, so what is its function, why is it visible in every area? So today we will know how a transformer works and we study the working principle of transformer. A Transformer  is a passive component that transfers electrical energy from one electrical circuit to another circuit or multiple circuits.                                                                     Or A Transformer  is an electrical device that transfers energy from one electrical circuit to another using the principle of electromagneti...

Today we are discussing the principle of a potentiometer. And also see how a potentiometer works. Before all this, let us know what is potentiator and where do we use it.  A  potentiometer  is a three-terminal  resistor having either sliding or rotating contact that forms an adjustable voltage divider.  Out of the three terminals - one is varying, whereas the rest two are fixed. The Potentiometer is an electric instrument used to measure the EMF(electromotive force) of a given cell, the internal resistance of a cell. It is the device used to compare the EMF of two cells. It connects with a cell whose emf is known or other supply sources. Comparing an unknown voltage with a known one gives you an unknown voltage. So we got to know what is a potentiometer and we will talk about its use in the last, Now let's see how it works , and what is the principle of a potentiometer   More About Potentiometer The potentiometer is also known as an Ideal voltmeter. ...

Nowadays the sales of air conditioners increase as soon as the summer season comes because everyone wants to enjoy air conditioner cooling in summers. You yourself will know how much fun it is to sit in the air conditioning room in the summer. But everyone enjoys it but how does it work. Is the principle of the  air conditioner working? Photo by Annie Spratt on Unsplash Today we will discuss the principle of an air conditioner working. firstly we have discussed an Air conditioner then discuss working. What is an Air conditioner? Air conditioners are basically refrigerators whose refrigerated space is a room or a building instead of the food compartment. A window air conditioning unit cools a room by absorbing heat from the room air and discharging   it to the outside.  An air conditioner can change the temperature, humidity or general quality of the air. More specifically, an air conditioner makes your home cool. Air conditioners work the same way as refrigerators. In...

Today everybody is interested in knowing about the  working principle  of refrigerator and how the refrigerator works. Nowadays, Refrigerator is very important, it has become a necessity for people. In the past era, food or other things could not be kept for a long time due to the lack of a refrigerator, but today we store food and other things for a long time in the refrigerator. First of all, we know about the refrigerator then we know how a refrigerator works and what is its working principle of refrigerator. What is Refrigerator? A  Refrigerator  is a household appliance that is used for keeping food and things cold. The refrigerator consists of a thermally insulated compartment and a heat pump. Generally, the temperature of the refrigerator keeps at or below 4° C because the Best temperature range for perishable food storage is 3 to 5° C. How does the Refrigerator work? The  transfer of heat  from a low-temperature medium to a high-tempe...
