Principle of air conditioner working : how air conditioner works?

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.

What's the principle of a Potentiometer- Physics

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. ...

Explain the working principle of transformer and also its construction - Physics

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...
