Free online courseElectrical Engineering Basics

Course Description

Understanding electricity opens doors to better DIY decisions, safer work practices, and new career paths in technical trades. This free online course helps you build a strong, practical foundation in electrical engineering basics, with clear explanations designed for beginners who want to move from guesswork to confidence.

You will learn how electricity behaves in real circuits, starting with the essentials behind conductors and insulators, current and voltage, and why materials like copper are widely used. Along the way, you will connect the concepts to everyday electrical protection and measurement, gaining familiarity with tools and components commonly seen in residential, automotive, and industrial environments.

As you progress, you will develop the ability to reason through circuit behavior using key principles such as Ohm’s law, conventional current versus electron flow, and the differences between series and parallel connections. These ideas become especially valuable when you start interpreting why devices behave the way they do, troubleshooting simple problems, or planning basic wiring tasks more thoughtfully.

The course also bridges core theory with the components that power modern systems. You will build intuition around diodes, inductors, relays, rectifiers, optocouplers, capacitors, and LEDs, understanding what they do and why they matter. You will explore how batteries store and deliver energy, how motors start and run, and how transformers support efficient power transmission—knowledge that translates across many jobs that touch electrical systems.

To round out your foundation, you will work with key power concepts like single-phase versus three-phase electricity, split-phase supplies, grounding, hot/neutral conductors, power factor, energy use in kilowatt-hours, and devices such as VFDs and starters used in motor control. With frequent practice questions to reinforce understanding, you will finish with a clearer mental model of electricity and the confidence to keep learning in the electrician and professional skills pathway.
