Electric Charge - Principles of Electrical Phenomena Summary:In this lesson, we will review the concept and origin of electric charge as the fundamental cause of electrical phenomena. We will start with a historical analysis where the Greeks observed electrical properties by rubbing amber with wool, leading to the law of...
Properties of Electric Charge and Atomic Structure In this class, we will review the concept and origin of electric charge as the fundamental cause of electrical phenomena. We will begin with a historical analysis where the Greeks observed electrical properties by rubbing amber with wool, leading to the law of...
Methods of Electrification by Contact, Friction, and Induction In this class, we will review the three methods of electrification: contact, friction, and induction. The atomic structure of matter is introduced, differentiating between conductors and insulators. It describes how bodies gain or lose electric charge through these methods, highlighting that induction...
Coulomb's Law and the Electrostatic Force The "Coulomb's Law and the Electrostatic Force" has not only expanded our understanding of electric forces but also generated unexpected anecdotes. Benjamin Franklin, during an experiment to stun and cook a turkey with electricity, ended up as the test subject: a discharge left him...
The Concept of the Electric Field In the 19th century, Michael Faraday, one of the greatest experimenters in the field of electricity, had a peculiar way of working: he filled his laboratory with wires, charged spheres, and small containers with conductive liquids. A famous anecdote tells that, in his obsession...
The Speed of Light and Electromagnetic Waves in a Vacuum Summary: In this class, we will review how, from the behavior of electromagnetic waves in a vacuum, it is derived from solving Maxwell's equations of electromagnetism in a vacuum. As a consequence, it is found that the speed of propagation...
