Atoms constitute the building blocks of all materials in existence. In these atoms, there is a central portion called nucleus (N in Figure 1) which consists of protons and neutrons, around which revolves the particles called electrons. Next, it is to be noted that all the electrons constituting the considered material do not revolve along the same path. However this even does not mean that their revolutionary paths can be random. That is, each electron of a particular atom has its own dedicated

An atom is defined as the smallest particle of a substance that can exist by itself or be combined with other atoms to form a molecule.In the year 1808, famous English chemist, physicist, and meteorologist John Dalton published his theory of the atom. At that time, many unexplained chemical phenomena got quickly unlocked by Dalton’s theory. Hence, the theory became a theoretical foundation of chemistry. The postulates of Dalton’s atomic theory were as follows. All matter is made up of small indi

It is introduced by Danish Physicist Niels Bohr in the year of 1913. According to this model the atom consists of small nucleus at the center and electrons which rotates in circular orbits surrounding the nucleus – similar to solar system. But here, the force of attraction is provided by electrostatic forces rather than gravitational forces. The nucleus is positively charged and electrons are negatively charged. Further Niels Bohr illustrated that the positively charged nucleus consists of proto

Understanding the short circuit definition and associated risks is crucial for ensuring electrical safety in homes and workplaces. By knowing the common causes of short circuits and employing preventive measures such as regular inspections, proper installation, and protective devices like circuit breakers and GFCIs, we can minimize the dangers associated with short circuits and create a safer environment for everyone.A short circuit phenomenon occurs in electrical circuits and poses potential sa

We all have seen plums in padding. Previously it was thought that electrons in an atom are distributed on positive charge just like plums in a pudding. In other words, it was thought that positive charge exists throughout the atom and negative electrons are unevenly distributed on it just like plums in the pudding. This concept of the atomic model is so known as plums in pudding model of atoms. This concept was introduced by J.J.Thomson who was also the inventor of electrons. As according to plu

he electronic configuration of an atom is a way of describing how its electrons are arranged in different energy levels and sublevels around the nucleus. The electronic configuration of an atom determines many of its physical and chemical properties, such as how it reacts with other atoms, how it conducts electricity, and how it behaves in a magnetic field.What is an Electron?An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. The nucleus consists of positi

Voltage drop (VD) occurs whenthe voltage at the end of a run of cable is lower than at the beginning. Any length or size of wires will have some resistance, and running a current through this dc resistancewill cause the voltage to drop. As the length of the cable increases, so does its resistance and reactance increase in proportion. Hence, VD is particularly a problem with long cables runs, for example in larger buildings or on larger properties such as farms. This technique is often used when

What is the Plum Pudding Model?Aplum pudding modelis a historical scientific model of the atom that was proposed by J.J. Thomson in 1904, shortly after he discovered the electron. The model tried to explain two properties of atoms that were known at that time: electrons are negatively charged particles, and atoms have no net electric charge.The plum pudding model suggested that an atom consists of a sphere of positive charge, called the pudding, with electrons embedded in it, like plums in a des

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. How much heat is generated during current flowing through a wire and on what conditions and parameters do the heat generation depend? James Prescott Joule an English physicist, coined a formula which explains this phenomenon accurately. This is known as Joule’s law. What is Joule’s Law of HeatingThe heat which is produced due to the flow of current within an electric

What is Alternating Current?Alternating current is a fundamental aspect of electrical systems that have shaped our world in countless ways. Its ability to be easily generated, converted to different voltages, and transmitted over long distances has made it the preferred choice for power transmission and distribution. Additionally, the many advantages of AC, such as compatibility with various devices and safety features, have made it indispensable in our daily lives.In the world of electricity, t
