Raspberry Pi For Beginners - 2022 Complete Course - The Resistors Color Code

This video tutorial explains the role of resistors in circuits, focusing on 1K and 10K resistors. It covers how to read resistor values using color codes, including both four-band and five-band resistors. The tutorial also provides guidance on selecting appropriate resistor values for different applications, particularly when working with LEDs and Raspberry Pi, to ensure safe current levels.

What should you do if you cannot find a 1 kilohm resistor in your kit?

Explain the relationship between resistor value and the number of LEDs you can connect safely.
