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. And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students Electric Charges. Electrons . can. . move. from one atom to another, but protons . cannot. move .. When an atom has . gained. electrons, it has more electrons than protons, and it is . negatively. 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.. By: Eman Mohammed Azizi. Introduction. . When you hear the word “electricity”, what comes to your mind? Maybe lightning, light bulbs, or even electronics. Well, for lightning to become lightning, or for a light bulb to become a light bulb, they need moving charges. The energy from the moving charges creates . Circuits. Electromagnets. Chapter 17 and 18. How can you produce electricity?.... right now!. The Law of Electric Charge. Like charges repel – push . away. Opposites attract. Electric Field. A region around a charged object in which an electric force is exerted on another charged object.. Chapter 20 & 21. Electricity. Electric charge . is a property that causes subatomic particles such as protons and electrons to attract or repel each other. . Protons have a positive charge.. Electrons have a negative charge.. Car Wash Systems. Adapted from presentation developed by Scott . Fausneaucht. Topics Covered. Definition of Electricity. Electrical Fundamentals. Generation & Transmission. Transformers. Fuses & Circuit Breakers. Electricity. . Movement of electrons. Invisible force that provides. light, heat, sound, motion . . .. Electricity at the Atomic Level. Elements. - The simplest form of matter . Atoms . - Smallest piece of an element containing all of the properties of that element. 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.

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 . Kevin Rolfe- Education Representative, Community Outreach. Claudine Truxal- Environmental Education Exchange. Robin Inskeep- STEM Coach, . Tolleson.
