Module No. 7 PHYSICS 322 Overview This module covers topics from the concept of electricity and its timeline, electric charge, electron theory of charge, conductors and insulators. Lisa enters her dark and quiet room. At a mere flick of a switch, light reveals the colorful surroundings. At the touch of a button, soothing music fills the air. With a single click, gentle breeze cools Lisa’s smiling face. Rapid developments in the study of electricity and magnetism in the nineteenth century led to amazing devices and machines that have radically changed our way of life. Electricity began with man’s curiosity on the peculiar ability of amber and lodestone is known today as magnetized iron ore. Amber is a translucent yellowish-brown fossil resin. As early as 600 B. C., the Greeks were aware that amber when rubbed vigorously with a piece of cloth could attract nearby objects. Much later William Gilbert named substances that attracts as electrics which comes from the Greek word electron meaning ―amber‖. The object is said to be electrified or is said to have acquired electric charge. Since the charge is at rest, it is often referred to as static electricity. Learning Outcomes At the end of this module, the students are expected to: 1. construct a timeline citing important concepts, laws, principles, inventions, and inventors in electricity 2. define an electrically neutral body, a positively charged body, and a negatively charged body 3. describe different ways of charging
