Electric current: Ohm’s law, resistivity

Introduction Electrical resistivity is one of the general properties  which determine the amount of resistance present in the element for electricity power. Resistivity is the reverse of the conductivity of electric power.  Electrical resistivity of Electric power  Electrical resistivity is the general property that almost all elements possess, electrical resistivity is the measure that determines […]

Electric current is defined as the rate at which charged particles such as electrons or ions move in a conductor or electric circuit. It is measured in Coulombs/second, which is known as Ampere. The SI unit of electric current is Ampere(A). Electric current is defined as the amount of charged particles passed through an electrical

The average velocity particles attained in a given material are caused by the applied electric field. When an electric field is present, electrons begin to move from the negative end to the positive end. The velocity with which the electrons travel is referred to as drift velocity. An electric field adds a little net stream

Introduction The Electric Current is a topic that holds various aspects of physics and describes the current flow and usage that we usually see in our daily lives. The study shows multiple uses of Electric Current and the definition to understand it clearly. Also, in this particular topic, other things include the Defining Electric Current

Almost all matter can be categorised into two main categories: conductors and insulators, based on how it reacts to electric current. Understanding the electrical characteristics of materials is critical since it aids in the construction of various electrical circuits and devices. The type of material used in a gadget has a significant impact on its

A route through which electric current flows is known as an electric circuit. An electric circuit can also be a loop if it is a closed path (both ends are connected). Because of the closed circuit, electric current can flow freely. An open circuit is one in which the flow of electrons is interrupted because

Electricity is derived from the word electron, which comes from the Greek word “Elektron,” meaning “amber.” In 1600, a philosopher named William Gilbert wrote a book called “The Amber Effect,” which detailed how the mineral Amber, used to produce jewellery, becomes encrusted with minute fibres of the cloth, making it difficult to wear as an

Electrochemical cells are devices that use the energy produced by a spontaneous redox reaction to generate an electric current. The voltaic, cell, galvanic named after Luigi Galvani and Alessandro Volta, is an example of this type of cell. During the late 18th century, these scientists experimented with chemical reactions using electric current. The anode and cathode are the two conducting

Have you ever gotten a minor shock when touching certain gadgets that are still in use? These shocks can be harmful at times, posing serious risks. To avoid mishaps, it is generally a good idea to have the building properly earthed. Earthing is the process of sharing electrical charges with the earth. Earthing is a

The negatively charged particles of an atom, which are called electrons, move. This leads to the generation of electric current and electric fields. Moving electrons create magnetic fields as well. The velocity gained by charged particles, such as electrons in an electric field, is known as the drift velocity. The movement of electrons resulting from
