Chapter 9: Current
9.1 Introduction to Electric Current Electric current is the flow of electric charge through a conducting medium, such as a wire or a circuit. The movement of charged particles, typically electrons, results in the transfer of energy and information through the medium. In this chapter, we will explore the properties and characteristics of electric current,…

Neutrons
Introduction Neutrons are subatomic particles that, along with protons, make up atomic nuclei. Neutrons are neutral, carrying no net electric charge. Basic Properties Neutrons are slightly more massive than protons. The mass of a neutron is approximately: Since neutrons carry no net electric charge, their electric charge is 0. Structure and Composition Neutrons are also…

Protons
Introduction Protons are subatomic particles with positive electric charge. They reside with neutrons within the atomic nucleus, with electrons “orbiting” around them. Basic Properties The proton carries a positive charge, denoted as , where is the elementary charge. The value of the elementary charge is: The mass of a proton is significantly greater than that…

Millikan Oil Drop Experiment
Introduction The Millikan Oil Drop Experiment was a groundbreaking experiment conducted by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). This experiment provided the first precise measurement of this fundamental physical constant. The Setup The experiment involved observing tiny oil droplets between two horizontal…

Chapter 2: Electric Fields
2.1 Introduction to Electric Fields Electric fields are all around us. An electric field is a region surrounding a charged object where another charged object experiences a force due to electrostatic attraction or repulsion. The electric field () is a vector quantity, meaning it has both magnitude and direction. The electric field is defined as…

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 Field
The electric field is a concept which describes the influence that a charged object exerts on other charged objects around it. More specifically, it is a vector field that determines the force experienced by a charged particle when placed in its vicinity. Basic Concepts of Electric Field The electric field is a vector field that…

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…
