The Topic of Electricity (!) hm C mfrts The Topic June 29 of Electricity 2016 Teachers’ Notes for the S1 Electricity Unit at Lockerbie Academy. This is a collection of the documents in the Resources files with a few additions from J A Hargreaves on how she teaches the material. This does not make it fixed that this is the only way to teach. This is the things I have taught the topic over the years. If we follow it to some extent, using the same terms etc. it will give all students a similar experience and give confidence to staff who may feel a little out of their depth with the physics. As usual this is an application and skills led course and it is as important for students to learn practical skills and confidence as they are to learn the content. Please do as little talk and chalk as possible. Try not to print!

  • Electrostatic Van De Graaff Electron Accelerator
    Engineering aspects of a 2MeV Electrostatic Van de Graaff Electron Accelerator. By: Ramiro G. Rivadeneira Texas A&M University Department of Biological and Agricultural Engineering Electrostatic Accelerator History Physicists developed machines capable of accelerating particles to study particle interactions from non-radioactive materials in the early 1900’s. R.J. Van de Graaff, an American scientist, in 1931 invented the electrostatic electron accelerator. Such an accelerator uses high-voltage to produce beams of electrons that can be directed to a target. Fundamentals of Charged Particle Acceleration The study of particle beams of any kind is called particle dynamics. This branch of physics will make it possible to understand the principles of accelerating electrons used by the Van de Graaff particle accelerator. How do we accelerate a particle? In order to accelerate a particle: Its kinetic energy E needs to increase. How? By change in its momentum P. Therefore a charged particle is accelerated when a change in its momentum occurs, produced by an electric field E. Then: dP [1] x = F = qE dt x x Now, consider an electron traveling between two parallel plates at a potential difference V. Uniform Electric Field, E KE , V KE , V 2 2 1 1 F=qE vx me , q Fig 1. Electron acceleration in a uniform electric field E between two parallel plates. The force Fx (Lorentz Force) experimented by the electron is given by: [2] F = q(v × B + E) Where E is a uniform electric field between plates, and B is a magnetic field. Change in Kinetic Energy As an electron moves from point 1 to point 2, its kinetic energy changes by: r 2 r 2 [3] ∆E = ∫ F ⋅ dr = q ∫ (v × B + E) ⋅ dr r1 r1 However, because of the uniform electric field E, the path velocity vector vx is parallel to the path vector dr, then the cross product (v x B) dr = 0 It can be seen that magnetic fields then do not change the particle energy E, thus particle acceleration depends only on the uniform electric field E.

  • Lab 1 Electrostatics
    Electrostatics Goal: To make observations of electrostatic phenomena and interpret the phenomena in terms of the behavior of electric charges. Lab Preparation Most of what you will see in this lab can be explained simply by the following: Like charges repel and unlike charges attract. These repelling and attracting forces that occur can be found using Coulomb’s law, which is stated as !! !! � = � !! where F is the electrostatic force, k is the Coulomb constant (8.99 x 109 Nm2/C2), q1 and q2 are the charges the objects carry, and r is how far apart the objects are. A neutral atom of a substance contains equal amounts of positive and negative charge. The positive charge resides in the nucleus, where each proton carries a charge of +1.602 x 10-19 C. The negative charge is provided by an equal number of electrons associated with and surrounding the nucleus, each carrying a charge of -1.602 x 10-19 C. Macroscopically sized samples of everyday materials usually contain very nearly equal numbers of positive and negative charges. When some dissimilar materials are rubbed together, some charges are transferred from one material to the other leaving each object with a small net charge. For example, when a glass rod is rubbed with silk, the rod usually ends up with a positive charge and the silk ends up with a negative charge. Materials can be cast into two electrical categories: insulators and conductors. The atomic or molecular structure of the material determines whether some charges are free to move (a conductor, such as metallic materials) or largely fixed in place (an insulator).

  • Van De Graaff Generator Safety
    Van de Graaff Generator Safety Introduction SCIENTIFIC Van de Graaff generators build up and maintain a high voltage static electric charge—some of SAFETYFAX! them up to 500,000 volts. Safely operating a Van de Graaff generator is essential if students are to have the opportunity to see the many exciting and memorable static electricity demonstrations performed with a Van de Graaff generator. Concepts • Van de Graaff generator safety • Static electricity Materials Van de Graaff generator Meter stick, wood (no metal), or 1-m wooden dowel (optional) Discharge electrode How a Van de Graaff Generator Works Most Van de Graaff generators build up a positive electric charge on their domes by separating negative electric charge from positive electric charge. This is accomplished by a rotating insulated belt. When two different materials are rubbed together, one object takes away electrons from the other object. The electron-removing object becomes negatively charged, leaving the second object with a positive charge. The tendency of an object to become positively or negatively charged is a property of the materials being rubbed together. In a Van de Graaff generator, the lower pulley connected to an electric motor rotates a rubber belt that is also looped over the upper metal pulley. The lower pulley and belt rub together causing electric charge transfer and separation. The lower pulley becomes negatively charged and the inside of the rubber belt becomes positively charged. Because the rubber belt is an insulator and not a very good conductor of electricity, the positive charge does not evenly distribute over the belt. Instead, the inside of the belt remains positively charged, while the Figure 1.

  • Van De Graaff Generator
    Van de Graaff Generator Mike Marchese H1 4/19/10 Introduction A Van de Graaff generator is an electrostatic device capable of producing very high voltages while maintaing a smaller, constant current. The first Van de Graaff generator was built in 1929 by Robert J. Van de Graaff, American physicist and inventor. This first model produced voltages of around 80,000V. Only two years later, Van de Graaff and his research partner Nicholas Burke constructed a larger generator capable of much higher voltages (about 7 million volts). This groundbreaking feat earned Van de Graaff a research fellowship at MIT, the position of director of the High Voltage Radiographic Project during World War II, and the T. Bonner Prize from the American Physical Society in 1965 (“History of the Van de Graff Generator”). Aside from its use in educating physics students about the properties of electrostatics, the Van de Graaff generator has been most frequently implemented as a power supply for particle accelerators. Van de Graaff-powered x-ray machines have been used for imaging and medical treatment (Beaty). Van de Graaff generators can also power the process of food sterilization with gamma radiation. Before the invention of more powerful, modern particle accelerators like the Linear Accelerator Ring and Cyclotron, the Van de Graaff generator played a central role in nuclear physics by powering proton collision for radioactivity research. The generator was also at the forefront of particle physics research before being rendered obsolete by the Pelletron VG generator, an improvement upon the original design that utilized a chain of conductors and dielectrics (“Van de Graaff Generator”).

  • 1) What Is Van De Graaff Accelerator?
    Q1) What is Van de Graaff Accelerator? Answer: Type of high-voltage electrostatic generator that serves as a type of particle accelerator. This device has found widespread use not only in atomic research but has numerous applications in medicine and industry. Q2) Who was Van de Graaff? Answer: Robert Jemison Van de Graaff is an American Physicist who was born on December 20, 1901 in Tuscaloosa, Alabama. His mother was Minnie Cherokee Hargrove and his father was Adrian Sebastian Van de Graaff. Robert attended the Tuscaloosa public schools and then attended the University of Alabama where he received a BS degree in 1922 and an MS degree in 1923. Both degrees were in mechanical engineering. He studied at the Sorbonne in Paris from 1924 to 1925 and while there, attended lectures by Marie Curie on radiation. In 1925 he went to Oxford University in England as a Rhodes Scholar. At Oxford he received a BS in physics in 1926 and a Ph.D. in physics in 1928. While at Oxford, he became aware of the hope of nuclear experimenters such as Ernest Rutherford, that particles could someday be accelerated to speeds sufficient to disintegrate nuclei. By disintegrating atomic nuclei much could be learned about the nature of individual atoms. It is from these ideas that Robert Van de Graaff saw the need for a particle accelerator He invented the Van de Graaff generator back in October of 1929 at Princeton New Jersey. Q3) How would the Van de Graaff accelerator operate? Answer: A high potential difference is built up and maintained on a smooth conducting surface by the continuous transfer of positive static charges from a moving belt to the surface.

    Washington University in St. Louis Electrostatics Lab Introductory Physics Lab Summer 2018 Electrostatics: The Shocking Truth STOP Important health warning for students with pacemakers or other electronic medical devices: This lab involves the use of a Van de Graaff generator, which produces small amounts of electrical charge. They are regularly used in elementary schools, high schools, colleges, and science centers. They pose no risk to health or safety, except to students with pacemakers or other electronic medical devices. If you use a pacemaker or other electronic medical device, please contact the Lab Manager, Merita Haxhia at [email protected], IMMEDIATELY to make other arrangements for lab. It is very unlikely that you will be affected, but safety is our top priority. As long as you do not have this type of medical device, you have absolutely nothing to worry about. However, it is not recommended that you bring sensitive electronic equipment to this experiment. Pre-Lab: The Van de Graaff Generator A Bit of History The Van de Graaff generator is an electrostatic generator, capable of producing constant electric potential differences reaching about 10 million volts. The model that you will use (thankfully) only achieves about 1% of that. The term Van de Graaff electrostatic generator may sound a little foreign, but there is one electrostatic generator that you are no doubt familiar with: earth’s atmosphere. In fact, some of the most famous experiments in the history of electrostatics were done using the atmosphere. In May of 1752, Benjamin Franklin performed his well-known kite experiment, an experiment which strongly suggested that lightning might not be so different from the sparks he produced using silk and glass.

  • Experiment 4 Van De Graaff
    Physics 6B Lab j Experiment 4 Van de Graaff APPARATUS • Heat lamp • Electroscope • Lucite rod and silk • Van de Graaff generator • Grounding sphere • Ungrounded sphere • Faraday cage • Faraday pail • Plastic box to stand on INTRODUCTION In this experiment, we will continue our study of electrostatics using a Van de Graaff electrostatic generator. If the electrostatics experiments were difficult because of humidity during the previous week, we will intersperse some of them with the experiments this week. ELECTRIC FIELD Consider an electric charge exerting forces on other charges which are separated in space from the first charge. How can one object exert a force on another object with which it is not in contact? How does the force move across empty space? Does it travel instantaneously at infinite speed or at some finite speed? In the 19th century, physicists suggested the beginning of a solution to these questions. Instead of imagining that the charge produces forces on other charges directly, they imagined that the charge fills the surrounding space with an electric field. When other charges are inside the electric field, they experience electrical forces. Electric fields can be visualized clearly by imagining that a small positive test charge is carried around, and the direction and strength of the force exerted on the charge are mapped. Think first about mapping the electric field of a single stationary positive charge. As we move the test charge around, the force is always directed radially outward from the stationary charge, and its strength decreases with distance from the stationary charge. If we draw arrows in the direction of the force, with lengths proportional to the strength of the force, we obtain a picture of the electric field similar to this: 1 Physics 6B Lab j Experiment 4 These lines provide a very convincing picture of electric fields.

  • Low Cost Electrostatic Generators Made from Funflystick™ Toy
    Apparatus Competition 2009 AAPT Summer Meeting Ann Arbor, MI Low cost Electrostatic generators made from FunFlyStick™ toy Robert A. Morse St. Albans School, Mount St. Albans, Washington, DC 20016 202-537-6452 [email protected] Abstract The Fun Fly Stick™ electrostatics toy (about $30 from various sources) can be easily modified for use as an inexpensive table-top Van de Graaff generator, or as a dipole electrostatics generator for experiments with electrostatic circuits. The modified generator reaches about 60 kV, has a capacitance of about 6pF and is equivalent to a VDG with a diameter of about 12 cm. Construction of Apparatus: The Fun Fly Stick™ is a hand held Van de Graaff generator (VDG) run by two AA cells, with an internal belt giving a positive charge to a cardboard collector. Its intended use is to levitate lightweight shapes of aluminized Mylar™. The generator ground is a ring around the push button switch on the handle which grounds it to the operator. The generator charges the cardboard collector positively relative to ground. A small DC power supply (3V, 2 A) could be used to replace the batteries if desired. To convert it to a table-top VDG, remove the cardboard collector tube and replace it with an empty 23.5 oz pop top aluminum drink can (e.g. Arizona™iced tea can) pushing the mouth of the can over the end of the Fun Fly Stick™ with the can tab contacting the collector brush on the Fun Fly Stick™. Wrap the handle with heavy duty aluminum foil so the foil covers the push button switch.
