🔍 How to Find LED Polarity Without a Multimeter! 💡 #shorts

Cut LED legs and no multimeter around? Don’t guess the polarity—learn how to visually identify the anode and cathode by looking directly inside the hardware! 🔍⚡

In this quick electronics engineering tutorial, we reveal how to find the positive and negative terminals of a light-emitting diode (LED) simply by inspecting its internal structure. By understanding the mechanical design—where the larger metal frame (the anvil) acts as the cathode for heat dissipation and chip support, while the smaller post acts as the anode—you will never rely on rote memorization again. Whether you are working on DIY electronics projects, PCB soldering, or circuit design, master the fundamentals like a pro engineer.
