This video explains semiconductors—materials whose electrical conductivity lies between that of conductors and insulators. Semiconductors are essential components in modern electronic devices.

2. Diodes & LEDs

Diodes & LEDs Tutorial

This video explains how diodes and LEDs work, how to distinguish between the anode and cathode, and how to use them correctly in electronic circuits.

IMPORTANT NOTES WHEN USING LEDS

IMPORTANT:

• Anode (the longer leg of an LED) – Connect to the positive (+) terminal.
• Cathode (the shorter leg of an LED) – Connect to the negative (−) terminal.
• A current-limiting resistor must be used when connecting an LED to prevent excessive current from damaging it.
