Electronics Basics #01 | Introduction to Diodes: Si/Ge/Ideal + I-V Curve

Instructor: Dr. Süleyman Burak ÇELİK

First lesson in the Electronics Basics series. Topics covered: • What is a diode? — anode, cathode, the colored band trick • Silicon model — V_F = 0.7 V, ON/OFF circuit equivalents • Germanium model — V_F = 0.3 V, when you'll see it in the wild • Ideal diode — perfect switch, when to use this simplification • I-V characteristic curve — comparing all three models on one graph We deliberately skip the deep semiconductor physics in this intro lesson — focus is on the working models you'll actually use to solve circuit problems. The next lesson dives straight into worked examples (forward/reverse bias, multi-diode networks). 🌐 AcEdumy.com
