PPT-Circuits and Electrical Current

Essential Questions for Circuits What are the requirements of a circuit What is actually going on in a working circuit What variables affect what other variables in a circuit What laws and formulas govern the relationships between these variables. N:2-3 / Series and Parallel Circuits. It’s a cool, clear night as you stroll by the harbor with your family. . The night is dark, but the waterfront is bright thanks to the thousands of twinkling white lights that outline the tall ships. . p730 - 735. Essential Questions. How does the wiring in a circuit change its ability to supply power to devices?. How do we represent physical circuit elements in schematic drawings?. Objective(s. ): . Volt. - Is the measurement unit of the electrical potential. . Electrical Potential. - The difference of voltage between two points in a circuit. It is the cause of the flow of a current. . Current- . Ms. Kammerer. Circuit Diagrams. An . electric circuit. is a complete path through which charge can flow.. Symbols are used to represent parts of a circuit. Source of electrical energy. Devices that are run by the electrical energy. and Ohm’s Law. The basics of electrical measurement. . Voltage is electrical pressure, which is potential force or the difference in electrical charge between two points. Voltage pushes electrical currents though a wire but not through its insulation.. Essential Questions for Circuits. What are the requirements of a circuit?. What is actually going on in a working circuit?. What variable(s) affect what other variable(s) in a circuit? What law(s) and formulas govern the relationship(s) between these variables?. Electric Current - . Flow of electrons through a material. Electrical Potential – . Similar to potential energy . Remember PE is . llifting. something higher against the force of gravity gives it greater potential to do work, increasing its potential energy.). Pre-Activity Discussion. © 2014 Project Lead The Way, Inc.. Digital Electronics. This Presentation Will…. 2. Introduce you to basic circuits and their symbols.. Introduce you to components and equipment that are fundamental to understanding circuits.. What we’re now learning:. Series Circuit. A . series circuit . has a single path for the current. Series Circuit. There is only one path for the electrons to flow. This means the . current must flow through all loads. but I will post the study guide this weekend. Problem 31. 31. (II) (a) What is the potential difference between points a and d in Fig. 26–49 (similar to Fig. 26–13, Example 26–9), and (b) what is the terminal voltage of each battery?. Activator. Essential Question:. How are series and parallel circuits similar and different in how they transfer energy. ?. Standard:. S8P5b. . Demonstrate the advantages and disadvantages of series and parallel circuits and how they transfer energy. Tips for Passing Inspection. George Mellors. Teacher Engineering former Industrial Engineer. Electrical Safety (Hazards). Electrical Components. System Design/Planning. Resources. Questions. Agenda. Based in Australia, Electrical Courses Perth is the top electrical training institute for studying the nationally accredited electrical training courses. We offer nationally-recognised, government-funded Electrical courses, EEHA courses, Electrical Instrumentation courses, etc. in Perth. Direct current (DC) circuits involve current flowing in one direction.. In alternating current (AC) circuits, instead of a constant voltage supplied by a battery, the voltage oscillates in a sine wave pattern, varying with time as v=V sin .
