Course content

1 section • 9 lectures • 30m total length

Introduction1:15
Learn by building circuits and observing diode behavior in simulation, from current flow and blocking to ac signal shaping and dc voltage regulation, including Zener diodes.
Building the First Diode Circuit3:11
Build a simple diode circuit with a 5V source and a 1K resistor to observe how anode and cathode orientation controls current, prefiguring conduction and blocking.
Forward Bias and Reverse Bias2:33
Understanding the Diode Voltage Drop3:25
Examine how a silicon diode imposes a forward voltage drop of about 0.7V in a 5V circuit, leaving 4.3V across a 1kΩ resistor and enabling rectification.
Half-Wave Rectifier4:14
Replace the DC source with an AC source, connect a diode in series with the load, and observe that only the forward-biased half-cycle reaches the resistor, creating a pulsating output.
Full-Wave Bridge Rectifier4:18
Smoothing the Output with a Capacitor2:40
Add a capacitor in parallel with load to smooth bridge rectifier output, reducing ripple as the capacitor charges at peaks and discharges between them, bringing DC closer to steady.
Zener Diode as a Simple Regulator4:08
Explore the Zener diode in reverse bias as a simple voltage regulator, with a series resistor to limit current, producing a near-constant output voltage around the Zener value.
Final Review4:36
Explore diode orientation, forward and reverse bias, and the silicon 0.7V drop. Build and simulate a full-wave bridge rectifier with a capacitor to reduce ripple, and study Zener voltage stabilization.

Requirements

No prior experience with diodes is required
Basic curiosity about electronics is enough

Description

Have you ever looked at a diode in a schematic and wondered what it actually does inside a circuit?

In this course, you will learn the fundamentals of diodes in a practical and visual way by building and simulating real circuits step by step.

Instead of focusing on heavy theory, this course is designed to help you understand diode behavior through observation and experimentation. You will see when a diode conducts, when it blocks current, how it affects voltage, and how it is used in some of the most important basic electronic circuits.

Throughout the course, we will use circuit simulations to explore topics such as:

diode orientation
forward bias and reverse bias
forward voltage drop
half-wave rectifiers
full-wave bridge rectifiers
capacitor filtering
Zener diode voltage regulation

This is a short and practical course, ideal for:

electronics beginners
engineering students
makers and hobbyists
embedded systems learners
anyone who wants to understand diodes without getting lost in complex semiconductor physics

By the end of the course, you will be able to look at a simple diode circuit and understand what is happening, why it is happening, and how changing the circuit affects the result.

If you want a fast, clear, and simulation-based introduction to diodes, this course is for you.

Who this course is for:

Basic curiosity about electronics is enough
Engineering students learning circuit fundamentals
Embedded systems developers who want stronger hardware intuition
Hobbyists and makers interested in understanding real circuits
Anyone who prefers learning by simulation instead of heavy theory
