In PHY 108 we will study the laws of electricity and magnetism (EM) These are described by four equations known as “ Maxwell’s equations ”. They are: 1. Gauss’s law for the electric field (Coulomb’s law) 2. Gauss’s law for the magnetic field James Clerk Maxwell 3. Faraday’s law 4. Ampere’s law Note: Maxwell’s equations describe experimental results

Chapter 21 Electric Charge In this chapter we will introduce a new property of matter known as electric charge ” (symbol q ). We will explore the charge of atomic constituents. Moreover, we will describe the following properties of charge: - Types of electric charge - Forces among two charges (Coulomb’s law) - Charge quantization - Charge conservation (21-1)
