2 Circuit Design What Is a Circuit? Circuit Diagrams Series Circuits
PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Circuit Design What Is a Circuit? Circuit Diagrams Series Circuits Parallel Circuits Combination Circuits This presentation is intended to be used with Project Circuit Design.

3 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics What Is a Circuit? A system of conductors and components forming a complete path for an electric current, consisting of three parts: Source of Electrons Pathway Load Device

4 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics What Is a Circuit? A system of conductors and components forming a complete path for an electric current. If the path is broken anywhere in the circuit, current stops flowing. How many ways could the path be broken in the image below?

5 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Circuit Diagrams A drawing that traces the path that electron flow will take in an electronic circuit Electronic components and functions are represented by symbols. Draw a map from the school to your house or some other destination. How did you draw roads, buildings, the school? What other symbols did you create? In an electronic circuit diagram, the roads are like wires. The buildings, houses, etc. are like components. Purpose of this slide is to get students to start thinking about using symbols and “maps” to show directions instead of words.

7 Series Circuits A circuit that contains only one path for current flow
Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Series Circuits A circuit that contains only one path for current flow If a component is removed, the path is opened and current cannot flow to any components.

8 Series Circuits A circuit that contains only one path for current flow
Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Series Circuits A circuit that contains only one path for current flow If the path is open anywhere in the circuit, current stops flowing to all components.

9 Series Circuits A circuit that contains only one path for current flow
Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Series Circuits A circuit that contains only one path for current flow Sketch a schematic diagram of this circuit in your engineering notebook.

10 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Parallel Circuits A circuit that contains more than one path for current flow If a component is removed, then it is possible for the current to take another path to reach other components.

11 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Parallel Circuits A circuit that contains more than one path for current flow Sketch a schematic diagram of this circuit in your engineering notebook.

12 Combination Circuits Contain both series and parallel arrangements
Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Combination Circuits Contain both series and parallel arrangements What would happen if you removed light 1? light 2? light 3? 1 2 3

13 Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Combination Circuits Sketch a schematic diagram of this circuit in your engineering notebook.

14 Your Turn! Build the three circuits just drawn in your binder.
Circuit Design PLTW Gateway® Unit 6 – Lesson 6.2 – Electronics Your Turn! Build the three circuits just drawn in your binder. Use the 6 volt side of the power supply. Before disassembling your circuit, be sure to answer all questions, and have your instructor verify your work.
