🌈 Resistor Color Calculator 🌈
Welcome, young engineers! 🧠 A resistor is like a traffic cop that controls the flow of electricity. The colored bands tell us how much the resistor will slow down the electricity. Let’s decode these colorful bands together!

Did You Know? 🤔
The colors of resistor bands were chosen to match the rainbow order (except for a few additions): Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey, White. This makes them easier to remember!
