Coulomb’s law, electric field and potential

Cells are being used for many purposes in the laboratory setup. The potentiometer is a piece of equipment to find the difference between the electromotive force of two cells and create a comparison between the two. It works on the principle of potential difference between two junctures of any cable, which is directly proportional to […]

The friction between a positive charge and a negative charge causes the electricity to move through them. A conductor acts like an open space where this phenomenon can occur more freely. The phenomena of electricity cannot be fully understood without first understanding the structure and makeup of atoms and molecules. Electricity is created when charges

A dipole is a pair of equal and oppositely charged poles separated by a distance. Electromagnetism has two forms of dipoles, electric dipoles, and the other dipoles are magnetic dipoles.  A dipole is measured in terms of its dipole moment. A dipole is formed as a result of the uneven sharing of electrons. An electric

Electric dipoles are vital for understanding electrical phenomena in materials. We know that matter is made up of atoms and molecules, each of which has both positively and negatively charged nuclei. It has an internal or permanent dipole moment if the centre of mass of the positive nuclei coincides with the negative nuclei. The dipole

In the year 1929-30, scientist Lawrence invented a particle accelerator device called the cyclotron. A cyclotron contains a hollow cylinder divided into two Dees in a vacuum chamber in which the charged particles are accelerated under the influence of an electric field along a spiral path. Principle of cyclotron:- The working principle of a cyclotron

An equipotential surface is an area in which all the potential charges of various points are the same. This makes the electrostatic forces that usually act on charges completely null and void, making the charges move freely without any disturbance. Hence, the work done in moving two points in an equipotential surface is zero. The

The generator is named after Robert J. Van de Graaff. He was an American physicist. When two materials are rubbed together, depending on their triboelectric properties, an electron flow can occur. Static electricity is the result of a substance losing its electrons and becoming positively charged and a material gaining electrons and becoming negatively charged.

Electric charge is all around us, and there are several pieces of evidence to support this claim. Have you ever rubbed cotton on a towel and then brought it to your hair? You will see that a portion of your hair is drawn towards the cotton, connected mainly by electricity. We’ll explain the behaviour of

We are surrounded by electrical charges in our daily life. When you rub a comb over a towel and bring it close to your hair, a portion of your hair will cling to the comb. This is because of the electrical charge. Let’s look at how opposite charges behave when kept at a distance from

In the year 1929-30, scientist Lawrence invented a particle accelerator device called the cyclotron. A cyclotron contains a hollow cylinder. This cylinder has two Dees in a vacuum chamber. An electric field accelerates the charged particles along a spiral path in this cylinder. Principle of Cyclotron The working principle of a cyclotron is that the
