PPT-Chapter 34 – Current electricity

The Physical World Building Blocks Objectives To help students understand construct and draw some simple electric circuits To ensure that students know how to measure voltages potential difference and currents in simple circuits. Unit 15. Today’s Concept:. . Ampere’s Law. Unit 15. , Slide . 1. Electricity & Magnetism Lecture 15, Slide . 2. We know for an infinite current carrying wire. Ampere’s Law. But what is . 2. and . Magnetism. Module 6. What is electricity?. The collection or flow of electrons in the form of an electric charge. What is . static. electricity?. When two objects rub against each other electrons transfer and build up on an object causing it to have a different charge from its surroundings.. What is ?. TED = The Energy Detective . Home Electricity Monitor. Installs in the breaker panel. Displays real time electricity information. Provides dollar amount of electricity. Projects monthly usage to predict bills. The next few slides are not on your note. They are just interesting. Electric Fish, Eels, and . Rays. For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . Electric . Power, AC, and DC Electricity. Key Question:. How much does electricity cost and what do you pay for?. *Students read Section 20.3 AFTER Investigation 20.3. Electric . Power, AC, and DC Electricity. Their Applications. An Engineer’s Simplified Model. William A. Stapleton, Ph.D.. Ingram School of Engineering. Texas State University – San Marcos. Models. Scientists attempt to understand the way the world works. . Kevin Rolfe- Education Representative, Salt River Project. Sarah Sleasman- 4. th. Grade teacher, . Excelencia. Elementary. Robin Inskeep- STEM Coach, . Tolleson. School District. Agenda . Introductions and logistics. Magnetism from electricity. In 1820, Danish scientist . Hans . Christian . Oersted. discovered accidently that when electricity passed through a wire…a magnetic field was created. Which way would the compass needles point if we placed them around the wire?. Electric Current:. RECALL: In static electricity, an electric charge . stays . in one area. . In current electricity an electric charge moves through conductors along a path. Its . electrons. that move NOT . An object that does NOT conduct electricity…. insulator. The measure of how much a material opposes the flow of current…. resistance. A circuit that has only one path that electricity can follow…. Kevin Rolfe- Education Representative, Community Outreach. Claudine Truxal- Environmental Education Exchange. Robin Inskeep- STEM Coach, . Tolleson. Scott Greenhalgh- Science Chair, . Eduprize. Gilbert. Electricity Electric Current Currents are the rate that electricity flows thru a wire 2 types of currents: Alternating Current (AC) electricity flows back-n-forth like in a house Direct Current (DC) electricity flows in one direction like in a battery 17.1 . Electric charge and force. Chapter 17: electricity. Electric Charge. Electricity:. force . created by a difference in charges . (+, -) . due to gained or lost electrons. . Protons (+) are trapped in the nucleus, so moving electrons (-) are responsible for electricity. NOTE: I will be plugging grades now, if you have tasks not turned in including projects, please turn them in ASAP before the end of the Second Period today.. . Those who have finished all tasks can move on to today’s tasks..
