Class 12

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

A Van de Graaff generator creates static electricity. The current generated by a Van De Graaff generator remains the same, while the voltage changes according to the applied load.  There are mainly two types of Van de Graaff generators: one that uses a high-voltage power supply for charging and one that uses belts and rollers.

The effect of an electric field on basic particles is regulated by electric charge, which is an essential element of matter. Electric charge is made up of natural units that can neither be made nor destroyed. The two forms of electric charges are positive and negative charges. When two things with an overload of one

Dielectrics are materials that are very poor conductors of electric current. These are materials in which the outer electrons are firmly bound to their respective nuclei. These electrons cannot leave the nucleus, even if they can be pulled towards a particular side of the nucleus. They are insulators and contain no free electrons. In stark
