LED Diagram Showing Anode and Cathode

This diagram provides a straightforward representation of a red Light Emitting Diode (LED). It illustrates the essential components, including the transparent dome and the two metal leads extending from the base. Critically, the image helps distinguish between the LED's anode and cathode terminals. The shorter lead is typically the cathode (negative), while the longer lead is the anode (positive), a common indicator for proper circuit connection. The symbol positioned above the LED, showing two dashes within a circle, further emphasizes the negative polarity associated with the cathode.
