PPT-Electrostatics

Prior Knowledge How have you experienced the effects of static electricity Electrical Nature of Matter Incredible as it may seem the act of rubbing a balloon against your hair doesnt create . In an equilibrium situation there cannot be an electric field inside a conductor as this would cause charges electrons or ions to move around Charge density inside a conductor is zero This follows from Gausss law As the charge density This does no r

Static electricity is electrical charges that can be collected and/or held in one place.. This is different from . current electricity. Also Known As. Static Electricity. Chemistry Refresher. Atom. the basic unit that makes up all . matter. Made up of protons, neutrons, and electrons. Chemistry Refresher. Proton. Part of an atom that has a positive charge. October 2012. Objectives.. To understand the basic properties of electric charge.. To describe the difference between conductors and insulators.. To calculate the electric force using . Coulumb’s. Law.. Units of Chapter 16. Static Electricity; Electric Charge and Its Conservation. Electric Charge in the Atom. Insulators and Conductors. Induced Charge; the Electroscope. Coulomb’s Law. Solving Problems Involving Coulomb’s Law and Vectors. Essential Knowledge. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. Lesson . 4. :. Uses of Electrostatics. (part 2). Starter. How many uses of electrostatics can you . recall. from last lesson. Look at the picture below, what do you think is the main topic of today’s lesson?. 1. When the balloon is rubbed on the sweater, what might happen?. A. . Some positive charges in the sweater will move onto the balloon. B. Some negative charges in the sweater will move onto the balloon. G S Peter Castle, LFIEEE and William D . Greason. , LFIEEE. Department of Electrical and Computer Engineering. Faculty of Engineering, University of Western Ontario,. London, ON, Canada . Origins. IEEE formed in 1963; amalgamation of American Institute of Electrical Engineers (AIEE) and Institute of Radio Engineers (IRE). phone for some research!. Do Now. In your notes:. Draw an atom of either Helium, Lithium, or Carbon. Label all the parts of your atom.. The first scientist to study these phenomena was Benjamin Franklin (1706-1790).. Tape lab (pt. 1). Make a tape “Flag”. Make a top (T1) and bottom (B1) tape sandwich. Make another pair of top and bottom tapes (T2 & B2). Directions. Hang T1 and B1 off the end of the table. (see figure below).
