Collecting Action of a Hollow Conductor

One of the most interesting and useful properties of conductors is their ability to collect and redistribute charges. A hollow conductor, in particular shows a special behaviour that is widely applied in electrostatic shielding, lightning arresters, and several modern electrical devices. This phenomenon is known as the Collecting Action of a Hollow Conductor. A conductor … Read more

Discharging Action of Sharp Point: Corona Discharge

In the study of electrostatics and electric fields, one interesting phenomenon is the discharging action of sharp points, It is commonly known as corona discharge. This effect is directly related to the distribution of electric charge on conductors and the intensity of the electric field around them. Discharging Action of Sharp Point: Corona Discharge It … Read more

Effect of Dielectric on Various Parameters

Capacitors play a significant role as devices for storing electrical energy. One of the most important concepts related to capacitors is the use of a dielectric medium. A dielectric is an insulating material that does not conduct electricity but can be polarised when placed in an electric field. Insulating material Effect of Dielectric on Various … Read more

Capacitance of a Parallel Plate Capacitor with a Conducting Slab

A capacitor is an essential device in electrical circuits used to store electric charge and energy. Among different types, the parallel plate capacitor is the simplest and most widely studied. Its capacitance normally depends on the area of the plates, the separation between them, and the medium (dielectric) between the plates. Electrical circuits Capacitance of … Read more

Dielectric Strength

Because dielectric materials can store electrical energy without conducting current, they have a specific role in the study of electrostatics and capacitors. The dielectric strength of these materials is one of their most vital characteristics. It is also widely used in electrical devices including transformers, insulators and capacitors. Capacitors What is Dielectric Strength? The highest … Read more

Dielectrics and Their Polarisation

In electrostatics, materials can be broadly classified into conductors and insulators. Conductors allow free movement of electric charges, whereas insulators (also called dielectrics) do not. Insulators Dielectrics play a crucial role in capacitors, electronic circuits, and various electrical devices because they can store and influence electric fields without conducting electricity. The study of dielectrics and … Read more

Redistribution of Charges

According to electrostatics, a conductor’s size, shape, and environment all affect how electric charges are distributed on it. Electric Charges When two or more charged bodies come into touch, the charges move around until they find an equilibrium state rather than staying fixed as they were before. The redistribution of charges is the term used … Read more

Energy Density of an Electric Field

In physics, energy is not just stored in visible or tangible objects it can also be stored in invisible fields. One such invisible storehouse is the electric field. Whenever there is an electric field present in a region of space, it can store energy. Electric Field This stored energy is an important concept in electrostatics … Read more

Energy Density of an Electric Field

Electric fields are a central part of electrostatics, and one of the fascinating ideas linked to them is that electric fields store energy. But how is this energy distributed in space? This is where the concept of energy density of an electric field comes in. What is Energy Density? Energy density refers to the amount … Read more
