What Is a Circuit?A system of conductors and components forming a complete path for an electric current, consisting of three parts:Source of ElectronsPathwayLoad DeviceSlide4
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?Slide5
Circuit DiagramsA drawing that traces the path that electron flow will take in an electronic circuitElectronic 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. Slide6

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.Slide8
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.Slide9
Series CircuitsA circuit that contains only one path for current flow Sketch a schematic diagram of this circuit in your engineering notebook.Slide10
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.Slide11
Parallel CircuitsA circuit that contains more than one path for current flowSketch a schematic diagram of this circuit in your engineering notebook.Slide12
Combination CircuitsContain both series and parallel arrangementsWhat would happen if you removed light 1? light 2? light 3?
