14. Lessons 1-3 Basic Electronic Theory, Resistor Color Code, Using the Solderless Breadboard Engineering01/EE/EE_presentation.pptx

15. Lesson 1: : Basic Electronics Theory • Comparing water systems to electronic theory is a good analogy to help understand Voltage (water pressure), Amperage (water flow), and resistance (valve/faucet) • Insure students understand it is only an analogy, it does not reflect what is actually happening • For all “Pencil Exercises”, write the questions ANDanswers in your LRB • Read Lesson 1 and do Pencil Exercises 1 & 2 Engineering01/EE/EE_presentation.pptx

16. Lesson 1 Ex. Answers • Ex. 1 • Draw and atom and label its parts • Ex. 2 • The use of different elements for the anode and cathode of the battery creates a force or voltage, • When you connect a lamp or any other conductive material across the terminals of a battery, electrons will flow from the negative to the positive terminal. • This flow is call electric current. Engineering01/EE/EE_presentation.pptx

17. Lesson 2 & 3 • Resistors, Resistance, Ohms • Read and do pencil exercises 1 & 2 • Using the Solderless Breadboard • Demonstration • Read then record the question and answer in LRB for the following: • “What happened to the LED when you made that change?” • “Explain why.” • Draw and label five rows of the breadboard • Circle the holes of one row which are connected to each other Engineering01/EE/EE_presentation.pptx

18. Lesson 2 Answers • Ex. 1 1. Resistance is the opposition to current flow. 2. Each resistor has a certain amount of resistance. 3. Resistance is measured in Ohms. 4. A resistor of 20,000 ohms will provide more opposition to current flow than a resistor of 5,000 ohms. • Ex. 2 • Red, Blue, Yellow, Gold = 260,000 Ohms, 5% tolerance • Blue, Green, Red, Gold = 6,500 Ohms 5%, tolerance • Brown, Black, red, Silver = 1,000 Ohms 10%, tolerance Engineering01/EE/EE_presentation.pptx
