LED Current Limiting Resistor Calculator - Why You NEED It!

Welcome to EIEverse! In this video, we're tackling one of the most fundamental yet critical tasks in electronics: correctly sizing a current-limiting resistor for an LED. Get this wrong, and you'll have a dead LED; get it right, and your circuits will be reliable and long-lasting!

Using a clear simulation, we break down exactly how to use Ohm's Law to calculate the perfect resistor value to protect your LED from overcurrent. Whether you're a beginner building your first project or someone who needs a quick refresher, this is a must-watch.

💡 In this tutorial, you'll learn:

The vital role a current-limiting resistor plays in an LED circuit.

A live simulation showing the current flow with the correct resistor value.
