Rutherford Scattering
Introduction Rutherford scattering is a phenomenon in physics that was used by Ernest Rutherford in 1911 to infer the presence of a positively charged nucleus at the center of the atom. The process refers to the scattering of particles by an atomic nucleus, leading to a deflection of the particles in various directions. Principles of…

Static Electricity
Introduction Static electricity is a phenomenon where electric charges build up on the surface of a material, typically an insulator or a non-conductor of electricity. This accumulation of charge remains in one area rather than moving or flowing away, thus termed as ‘static’. The effect is usually caused by friction, where contact between surfaces results…

Chapter 1: Electric Charge and Coulomb’s Law
1.1 Introduction to Electric Charge Electric charge is a fundamental property of matter. There are two types of electric charge: positive and negative. Objects with like charges repel each other, while objects with opposite charges attract each other. The fundamental unit of charge is the elementary charge which is the charge of a proton (positive)…

Electric Current
Electric current is the flow of electric charge, typically carried by charged particles such as electrons or ions, through a conductor or in a circuit. It is a fundamental concept in the study of electricity and is at the heart of countless devices and technologies, from power generation and distribution to electronics and telecommunications. Basic…

Electric Charge
Electric charge is a property of matter that gives rise to the electromagnetic force, one of the four fundamental forces in nature. It is responsible for the interactions between charged particles, such as electrons and protons, and is the basis for a wide range of phenomena, from static electricity to the flow of electric current…

Coulomb’s Law
Coulomb’s Law is vitally important in the field of electrostatics as it describes the force between two charged particles. This principle is named after the French physicist Charles-Augustin de Coulomb, who formulated the law in the late 18th century. Basic Understanding of Coulomb’s Law Coulomb’s Law states that the electrostatic force between two charged particles…
