Electrostatics

Coulomb’s law, Coulomb’s inverse-square law or electrostatic force, was discovered by Charles-Augustin. It calculates the amount of energy that exists between two particles that are electrically charged and stationary. The law is applicable only for the point charges at rest. The law states that the force existing between two charged particles is inversely proportional to […]

A system in which a pair of electric charges opposing charges separated by a distance d is known as an electric dipole. The electric dipole moment p is the product of any two charges multiplied by their distance. It moves from a negative to a positive charge. The axis of a dipole is the line

William Whewell was the first to coin the word “dielectric.” It comprises two words: ‘Dia’ and ‘Electric.’ A dielectric material is a substance that conducts electricity poorly but effectively supports an electrostatic field. An electrostatic field can store energy if the flow of current across opposing electric charge poles is reduced to a minimum and

The intensity of an electric field at a point due to a group of charges is equal to the arithmetic sum of intensities of an electric field due to each charge at the same given time. An electric field is a space around the electric charges where the force of either attraction or repulsion can

The universe is governed by various aspects such as force, acceleration, energy and charged particles. Each charged particle develops a unique electric field on the earth in the space surrounding it. The electric field developed because the charge is independent of the absence or presence of all different charges.  +e or –e is the smallest

The Van de Graaf generator can effectively make a very high voltage. Robert Jemison Van de Graaff designed it in 1929 A.D. it can generate a voltage in millions. It works by aggregating charge on an empty metal construction with a moving belt. This construction is designed in the shape of a globe and sits

A nonpolar molecule does not have any separation of charges. We can say that the electrical charge of a nonpolar molecule is distributed evenly within. Generally, these molecules are formed when the electrons are shared equally between the atoms in a molecule. They are also formed when the electrons inside a molecule are arranged symmetrically

A charged object’s behaviour depends on the kind of material it is made of, i.e. conductive or nonconductive. Looking at the conductor’s definition, you’ll learn that conductive materials are those that allow electrons to move freely from particle to particle. Thus, we call them conductors. On the other hand, insulators are those materials that do

A Van de Graff generator is a machine that is used to generate electrostatic charges. This machine was invented by American physicist Robert J. Van de Graff. It works on the principle of electrostatics. In short, it is an electrostatic accelerator that is used chiefly in nuclear physics research experiments to get high voltages in

Electric Potential definition is defined as the amount of work that is required to move a unit of electric charge from one referential point to a specific point in an electric field. Ideally, the reference point can be Earth or infinity. However, any point can be used.  The electrostatic field (E) is a vector quantity
