PPT-15.1 Electric Charge and Current

pp 340 345 Mr Richter Agenda Intro to Electrostatics Notes Charge and Net Charge Measuring Charge Electroscopes Charging Objects Three Ways Objectives We Will Be Able To Distinguish between a positive and negative net charge. Objective: TSW understand, transfer and apply energy concepts to electric fields and charges by solving problems involving electric fields and forces.. Let’s revisit energy concepts for a gravitational field. A 250 gram baseball is thrown upward with an initial velocity of 25m/s. What is the maximum height reached by the ball?. Introduction to Electricity. Let review…. All matter is made up of atoms.. Atoms are made of charged subatomic particles.. Electric charge is a fundamental property of matter, similar to mass.. The electromagnetic force exists between protons and electrons. Like charges repel. Opposite charges attract.. A. little. chemistry. . . . All. . matter. . . .

Controlled electricity is the cornerstone of our modern, technological society.. Chapter Goal: . To develop. a basic understanding of electric phenomena in terms of charges, forces, and fields.. A.S. 5.1.1 – 5.1.4 due Monday. Reading reference: chapter 16. Question 16.1a. . Electric Potential Energy I . a). . proton. b). . electron. c). . both feel the same force. d) neither – there is no force. Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. .

These collide with lattice ions . Electrons on an insulator (zoomed in).. Zoomed out – difficult to “see” individual electrons . smooth distribution of charge..  Like charge is “smeared” on the insulator.  . - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -.

The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . © 2014 Pearson Education, Inc.. Contents of Chapter 16. Static Electricity; Electric Charge and Its Conservation. Electric .
