Lab 1 - Flashlight - Jauary 12, 2023

Using breaboard, 9v battery, resistor and wires to illuminate LED in first circut

Prep / Notes

• Resistors are not polarized
• Gold stripe = 5% resistor
• Black, Brown, ROYGBV, Gray, White; 0-9

LED Layout

• Big piece of metal (anvil) is on negative side
• flat side is negative (not always on bigger LED’s)
• Shorter leg is negative (not always)

Process

• Drew schematic and diagram of planned circut

• Built circut - few complications

• Before connecting battery

Result

• After studying videos/pdf and taking detailed notes, I had success on the first attempt

Conclusion

• It was a relatively simple process to get this circut working
• The LED did seem a little bit dim, was there too much resistance?
• How do electricians know how much current a component can recieve? It is known that an LED can only take so much incoming power- is stuff like this standardized?
