Introduction Have you seen a bolt of lightning before a thunderstorm on rainy days? Did your elders tell you not to touch electronic devices with wet hands? You must have seen electronic appliances like a television, refrigerator, air conditioner, and mixer at your home. Do they work automatically? Or do they need some energy to work? Yes. This…

Introduction Carbon resistors are a type of resistance component used in electrical and electronic circuits to provide resistance to the flow of electricity, generally as a way to regulate current or voltage. There are multiple types of carbon resistors and each type has different features, functions, and uses that it performs well. Graphite or coke,…

Introduction Ampere Prefixes are commonly used while studying electrical circuits. There are seven fundamental units i.e. metre(m), kilogram (Kg), second(sec), Ampere(A), Kelvin(K), mole(mol), and Candela (Cd). Among these basic units, Ampere(A) is used to denote the flow of current. It is also noted shortly as the amp. There are many systems of units used such as the KGS…

Introduction We all have attended a lot of marriage parties or any celebration and unfortunately sometimes we face issues of power cut in between from the power grid. At that time, we need some power back up so that our work or celebration will not get stopped. So one of the very popular backups around…

Introduction Electric generator was discovered even before the discovery of the connection between electricity and magnetism. Moving electrically charged plates, disks, and plates were used to operate the electric generators and it follows electrostatic principles. The charge was mainly produced by using either of two mechanisms: turboelectric effect and electrostatic induction of turboelectric effect. Such kinds…

Introduction Electrical generators are also termed dynamo which is the machine that alters the mechanical energy into electricity for distribution and passing over the lines of power to commercial, domestic and industrial customers. DC generators are one of the major types of electrical generators. Generators help in generating the electrical power necessary for aircraft, ships…

Specifically, an electric dipole separates the positive as well as negative charges of a device. The behavior of the electric dipole mostly relies on the external electrical device. In the case of the placement of torque in a homogeneous electric device that denotes the E strength, the axis of the dipole forms an angle θ…

Introduction The idea of the electric generator was formulated far before the correlation between electricity as well as magnetism. This machinery particle is mainly operated by the electrostatic principles that guide to operate with the application of plates as well as moving belts. This particular form of generator is mainly used during the sudden current…

Introduction Static electricity is applied to multiple purposes in daily human lives starting from attractions between objects to repulsion between different objects. Static electricity is commonly generated when objects come into contact. As the electrons stay stationary during the attraction between objects, it generates static electricity in the process. Static ions can be seen through…

Introduction Electrical resistivity is known to be the reciprocal of electrical conductivity. Resistivity of various materials is mentioned through the function of temperature as it rises with temperature due to the electron-phonon connection. Resistivity of the material is restricted even at the ultimate zero due to the existence of small amounts of defects and impurities.…
