Current Electricity

Transformers have been designed to play a significant role in creating and distributing electrical power, which remains an integral element of human life’s daily use. Transformers are used to transfer electric current from one electrical circuit to another, as well as to control the current. Each electrical circuit in the transformer has a specific number […]

A DC generator is a device that transforms mechanical energy into direct-current electrical energy. This research will focus exclusively on this DC generator since it has been the most widely used part of the dc generator in the business. Many common terms, including generator motors, are encountered daily. DC generators are generally best suited for

An AC generator is an electrical device that produces electricity by converting mechanical energy into electrical energy. It converts mechanical power into electrical power by using electromagnetic induction. This is achieved by two major parts of an AC generator, a rotor (rotating part) and a stator (stationary part). Parts of AC Generator The parts of

Introduction Van de Graaff generator is a device that can create insulating effects in a conductor and ensure a high amount of insulation and high potential in various objects.    This chapter will include discussions to define the Van de Graaff generator. It will explain the various uses and Working principles of the Van de

Generators are widely used for converting mechanical energy of motive power into electricity, which is then used in electric circuits. These devices, often called generators, are utilised to convert mechanical energy to electrical energy. The electrical energy produced is used in the external circuit to generate electricity. Various mechanical energy sources are available, such as

Introduction A solar cell is an electrical device in which light energy gets converted into electrical energy by the photovoltaic effect.  It is basically a PN junction diode and is called a photovoltaic cell. The solar panel is formed by a combination of solar cells. The common junction will produce a maximum voltage of 0.5

A two-terminal electronic component that conducts the current(I) in one direction is called a diode. In diodes, the most commonly used diode is a semiconductor diode. In this article, the special types of semiconductor diodes like photodiodes, solar cells and Zener diodes with their internal construction, their types with the application are explained. Photodiode Photodiodes

A galvanometer is a sensitive device (or instrument) used to detect and measure the feeble (or weak) electric current passing via an electric circuit.  When an electric current flows through the coil in a constant magnetic field, the pointer of the galvanometer shows deflection. The amount of this deflection is proportional to the amount of

The galvanometer is used to detect small values of current in a circuit. The voltmeter is used to calculate the potential difference across a circuit. However, it is possible to convert a galvanometer into a voltmeter.  The voltmeter can be defined as an instrument used to measure the electrical potential difference across any two points

The charge transferred per unit time is the measurement of electric current. In conductive material, it represents the flow of electrons. Electric current is a scalar quantity, and its SI unit is Coulomb/Second. There are two types of current, namely (i) DC (direct current) and (ii) AC (alternating current). In DC, as the names suggest,
