Electronic Circuits Course by The Organic Chemistry Tutor

Sobre este curso

Strong circuit knowledge is a practical advantage for anyone working with electrical installation, maintenance, or electronics troubleshooting. This free online course helps you move from simply memorizing formulas to actually understanding what is happening in a circuit and how to predict results before you pick up the multimeter. You will develop the confidence to interpret real-world behavior in resistive, diode, and basic AC circuits, and to make safer, smarter decisions when designing, repairing, or verifying electrical systems.

You start by grounding your understanding in the essentials: electric current, voltage, and resistance, then connecting those ideas with Ohm’s law and power relationships. From there, the course trains you to analyze series and parallel networks and to apply Kirchhoff’s laws so you can solve multi-branch circuits with a clear, repeatable method. Instead of guesswork, you learn how to approach loop and junction problems logically, calculate expected currents and voltage drops, and check whether results make sense in practical terms.

As you progress, you explore how common components behave under different conditions. You will practice diode circuit analysis and see how forward voltage drop influences current, including typical situations like selecting a resistor for an LED. Power concepts are emphasized throughout, helping you estimate dissipation in resistors, diodes, and LEDs to avoid overheating and failure. The course also connects calculations to everyday electrical cost and consumption, making energy and kWh concepts immediately usable.

The later sections broaden your capability into AC fundamentals, including RMS vs peak values, impedance, reactance, and power factor. You will work with capacitive and inductive behavior and gain intuition for how frequency changes circuit response. Practical conversion topics are also introduced, such as rectification, basic filtering ideas, voltage regulation with Zener diodes, transformer relationships, and inverter power estimates. By the end, you will be better equipped to analyze circuits, size components more responsibly, and communicate electrical reasoning clearly on the job.
