Starting the Electric Circuits Textbook Series — A roadmap from zero to a field-ready foundation

If you've ever tried to "properly learn electricity" and ended up bouncing between fragments — a YouTube video here, a textbook chapter there — without ever feeling like the pieces connect, this post is for you.

I'm Bono. I run a YouTube channel and a blog around electronics, and from this week I'm starting a long-running series called the Electric Circuits Textbook. Its job is to take you from zero all the way to a foundation in circuit theory that actually holds up in the field — covering electric circuits, electronic circuits, logic circuits, and power electronics with control, in that order.

This article is the Episode 0 — an orientation before the main series begins. By the time you finish reading, you'll know who this series is for, how far it goes, what each of the four parts contains, and how to actually get through a long series without burning out.

Note on numbering. In the video version this is labeled as "#1," because YouTube counts the introduction. On the blog I'm calling it Episode 0, since the content of this article is roadmap-only — the actual material starts in the next episode.

Welcome

The Electric Circuits Textbook is a structured course that walks you through the theory of electricity from zero, in order, and systematically. Once the theory is solid, a separate practical edition is planned to follow.

I spent more than a month designing this series — deciding what to teach, in what order, and where to slow down. I've also gone through every piece of the content myself. So I'm shipping it with confidence.

This first article lays out the big picture: what we're going to learn, and how.

Who This Series Is For

You can start with middle-school-level math. That part is honest.

What I also want to be honest about: this is not a course you can follow with no math at all. Around AC, transient phenomena, and control, we use high-school-level ideas — trigonometry, complex numbers, calculus. I break each one down as it appears, so a non-STEM background, a beginner background, or a long-pause-and-restart background is all fine. You don't need to brace yourself before starting.

But it's also not a shortcut. Real understanding takes time working through examples yourself. With that caveat in mind, the series is especially aimed at:

• People who want to work in the field one day, and need a real foundation
• Self-learners and working engineers who want to rebuild from first principles
• Anyone who is willing to take it one step at a time

If that's you, I'll take you all the way.

Why I Made This Series

A short backstory. There are three reasons this series exists.

1. There aren't many beginner-friendly paths that put the pieces in order. I've been making electronics content on YouTube for years, and I kept seeing the same gap: plenty of individual lessons, but very little that walks you through circuit theory as one ordered sequence.
2. Demand in the field is growing. With AI everywhere and the working-age population shrinking, I keep hearing from both sides — companies that need people who can handle real electricity, and learners who want a way in. I want to help bridge those two.
3. The tools to make a proper textbook finally exist. I've wanted to build something like this for years but never had the bandwidth. AI as a writing and review partner is what finally made it possible.

How Far You'll Go

Where will you end up after the theory edition?

The goal is a theoretical foundation in electricity that holds up in the field. Not formula memorization. The aim is to understand the basic theory of electricity, electronics, logic, and control through the reasons behind each result, not just the result itself.

Concretely, that means:

• You can read what a circuit diagram and its symbols actually mean
• You can explain how a circuit works in your own words
• You can follow conversations and reference material that engineers exchange day-to-day

Component selection, measurement technique, and design judgment — the hands-on side — belong to the practical edition that follows the theory edition. The theory edition's job is to make sure that foundation is built solidly.

The Whole Map of the Series

The theory edition is structured as four parts.

1. Part 1 — Electric Circuits
2. Part 2 — Electronic Circuits
3. Part 3 — Logic Circuits
4. Part 4 — Power Electronics and Control

The order matters. Each part is the foundation for the next, so working through them front-to-back is the shortest path. And the theory edition doesn't actually stop at Part 4 — I plan to keep adding topics beyond it as the series grows.

Part 1: Electric Circuits

Let me walk through each part briefly.

Part 1: Electric Circuits. We start from the basics of DC circuits, work through Ohm's law and AC, and finish at transient phenomena that change over time. This is where you build basic stamina in electricity. Everything that follows rests on this part.

Part 1 — Contents

A closer look at what Part 1 covers.

It starts with the fundamentals of DC circuits — circuit symbols, current and voltage, and ground. From there we move to Ohm's law and the calculations around power and series/parallel resistance. Then the circuit theorems for solving circuits, then capacitors and inductors that store energy, then AC circuits. We close on AC power, three-phase AC, and transient phenomena.

Topic	What you'll get
DC fundamentals	Symbols, current, voltage, ground
Ohm's law and calculations	Power, series/parallel reasoning
Circuit theorems	Tools for solving real circuits
Capacitors and inductors	The energy-storage elements
AC circuits	Complex numbers as a working tool
AC power and transients	Three-phase AC, time-varying behavior

By the end of Part 1, you'll have the basic circuit intuition you need for the rest of the series.

If a word like "transient phenomena" looks intimidating, don't worry — that's a Part 1 topic and we walk into it from scratch with diagrams. Right now it's enough to know the word exists.

Part 2: Electronic Circuits

Part 2: Electronic Circuits. Semiconductors, diodes, transistors, op-amps — the components that do something to signals. You'll learn the techniques for handling signals: amplifying small ones, reshaping their form, generating new ones. This is where the insides of the electronic devices around you start to make sense.

Part 2 — Contents

Part 2 covers, in order:

1. How semiconductors and diodes work
2. Rectifier circuits and power supplies — turning electricity into clean DC
3. Transistor operation
4. Amplifier circuits — making small signals larger
5. Op-amps — the workhorse of practical amplification
6. Oscillators, modulation, and demodulation — generating and carrying signals

After this part, you'll know what each common component is for, not just what it's called.

Part 3: Logic Circuits

Part 3: Logic Circuits. This part shifts gears. Here, using only two numbers — 0 and 1 — we look at how the insides of a computer are actually built. You'll combine logic gates to compute and to store state. This is where you touch the deepest layer of the device you're reading this article on.

Part 3 — Contents

Part 3 has four chapters:

1. Binary and the basics of logic circuits — binary, Boolean algebra, logic gates
2. Combinational circuits — combining gates to compute
3. Sequential circuits and flip-flops — circuits that remember; counters and registers
4. Memory and AD/DA conversion — storage, and the bridge between analog and digital

By the end, you can see how a computer does both calculation and memory — the two things that make it a computer.

Part 4: Power Electronics and Control

Part 4: Power Electronics and Control. Everything you learned in Parts 1–3 — electricity, electronics, logic — gets used here. Power supplies, motor drives, and the control engineering that commands them. The power-supply circuits that convert electricity efficiently, the drive circuits that actually turn motors, and the control that makes them move the way you intend. This is the part where everything ties back to the real world.

Part 4 — Contents

Part 4 covers:

1. Power-supply circuits — DC-DC converters and switching power supplies, for efficient conversion
2. Motor drive — the various motor types and the circuits that drive them
3. Control engineering — fundamentals — the idea of feedback
4. System response and stability
5. PID control — the workhorse of practical control

By the time you get to the end of Part 4, you have the toolbox to drive a piece of physical hardware and command it the way you intend.

How to Actually Get Through a Long Series

A series this long needs three habits to survive. Keep these in mind:

1. Follow the episodes in order, along the map. Each block is the foundation for the next. Skipping breaks the chain.
2. When you get stuck, go back without hesitation. Almost every "I don't get it" has its cause one step earlier. Walking back is cheap; pushing forward confused is expensive.
3. One episode, one theme. Take it at your pace. Each episode is self-contained for that one theme, so it's perfectly fine to move slowly. Real ability builds either way.

It will feel hard at times. But it's designed so that if you keep moving — even slowly — you'll reach a place where it makes sense.

A Quick Note on Some Common Misconceptions

A few things readers often expect from an introduction like this. Worth clearing up before the main series starts:

What people often expect	What this is actually
The introduction teaches Ohm's law, basic circuits, etc.	This is the map only. Real content begins in the next episode.
"I'm not a STEM person, so electricity isn't for me."	The required math is filled in as it appears. You can start from zero, as long as you're willing to work through the math when it shows up.
"If I can't binge the whole ~140-episode series, there's no point."	Each episode is one self-contained theme. Go in order, back up when you need to, that's enough.

Where We Go Next

That was the Episode 0 — who this series is for, how far it goes, what the four parts contain, and how to actually get through it.

The most important takeaway: electricity, taken one step at a time in the right order, is reachable — for non-STEM backgrounds, for total beginners, for people coming back to it years later. If you want to follow technical conversations and read manufacturer documentation comfortably, this series is built for exactly that.

In Episode 1, the actual content begins: Electric Circuits and Schematic Symbols. We unpack what a "circuit" really means, and how to read a schematic diagram, starting from zero. See you there.
