Potentiometer: Principle and applications

Inventors started working on a brilliant idea that would change the way we utilise energy in our homes and offices more than 150 years ago. This idea revolutionised building design, lengthened the normal workday, and sparked the creation of new enterprises. It also resulted in new energy innovations, ranging from power plants and transmission lines […]

One of humanity’s greatest inventions is the electric motor. We would have been nothing more than shining bulbs with energy if it hadn’t been for the invention of the motor. Electrical energy is converted into mechanical energy by the electric motor. Electric motors are typically designed to rotate continuously. The electric motor, to be precise,

E.M.F. of a cell Maximum potential difference between two electrodes of a cell is known as E.M.F. (Electromotive force). Dynamic Induced E.M.F. is generated when a current-carrying conductor cuts the magnetic flux using relative motion. The magnitude of induced e.m.f is directly proportional to the negative rate of variation of the magnetic flux attached with

Introduction Photodiodes are the special type of semiconductor diodes that convert electrical energy into light energy when exposed to light. When the junction of the photodiode is illuminated, then the electric current flows through the two terminals. Only electrons flow through it in reverse bias. This is called the photoelectric effect. Symbol of photodiode Construction

When the current flows through the electrolyte present in an electrolytic cell, the solution offers internal resistance to the flow of the current across it. A potentiometer is a versatile instrument made up of a uniform wire connected across a standard cell. It is used to measure the emf of a cell and compare the

The primary cell’s electromotive force is the amount of energy created by the battery and after one usage, these cells are discarded. The potentiometer is a piece of equipment to find the difference between the electromotive force of two primary cells and create a comparison between the two. Let us understand more about this through

When different electrical devices are connected in a single circuit under the influence of some energy source, all of them are made to connect in a particular manner. One of how the devices are connected is known as a parallel connection and the other way is known as a series connection. All these connections are

A capacitor is a device that stores electricity in an electric field used by devices that need a large amount of energy to start. When two parallel plates are connected to a battery, they form a parallel plate capacitor that can store infinite electrical energy before the insulator or the insulating capacity breakdown of the

Electricity is a crucial part of modern lives, and hence when it comes to the generation of electricity, all big and small units rely on generators. A generator is a device that converts mechanical energy into electrical energy by generating alternating current. It can be of two types: AC generators and DC generators. An AC

What is a Potentiometer? Also known as a potentiometer or just a pot, a potentiometer is a device used to measure an unknown voltage. It does so by comparing it with the voltage that is known. The potentiometer is a long piece of wire that is cut into several pieces, across which a conventional cell
