Forging new generations of engineers

1. Creating Basic Bread Board Electrical Circuits Forging new generations of engineers

2. Basic Electrical Circuits Any arrangement of components that allows an electrical current to flow

3. A Basic Circuit A Source Battery Wire A Load Lamp Battery Lamp A Conductor Wire Switch A Control Switch There is only one path for the electrons to flow

4. Create our own Basic Circuit • You need • Base (what we are calling a bread board) • experimental circuits are called breadboarding Using a actual kitchen breadboard is ideal because it is a non-conductive surface nails could be used to create elecrical connection points for electrical components

5. AA AA Create our own Basic Circuit • You need • Straws • Cut into 1/3rds • Place support straws for the battery at (1,11) & (2,10) & (2,12) & (6,12) & (6,10) & (7,11) • Make battery holder • Using cut straws

6. Create our own Basic Circuit • You need Wire • We will make our own • Folded foil wires • Fold the foil to make a thin ribbon • Wrap the foil around strip of card board foil

7. AA Create our own Basic Circuit • You need • Cut folded foil wires into 2 sections 2 ½ in. long • Wrap the folded wires around the straws at the end of the batteries • Add more support straws (1,1) & (1,7) & • (6,1) & (1,7) & (6,7) • Wrap folded foil around the additional straws • Add christmas bulb with wires by • Wrapping the wires around folded wire ends • Now try your switch Christmas light Switch Straws

8. A Series Circuit Wire A Source Battery A Load 2 Lamps Battery 2 Lamps A Conductor Wire A Control Switch Switch Electrons can only flow along one path, and MUST go through each component before getting to the next one.

9. A Parallel Circuit A Source Battery A Load 3 Lamps A Conductor Wire A Control Switch Two or more components are connected so that current can flow to one of them WITHOUT going through another

10. A Series-Parallel Circuit A combination of components both in Series and in Parallel
