100 cards
This deck offers a friendly introduction to the core ideas every electrical engineering student or hobbyist encounters early on. It walks through the foundational relationships between voltage, current, resistance, and power, then expands into circuit analysis with Kirchhoff's Current and Voltage Laws. You'll also find cards that distinguish between direct and alternating current and explain how RMS and peak values relate to one another, which is essential for understanding real-world power supplies.
The cards are well suited for beginners who are just starting a course in circuits or electronics, as well as self-learners who want a quick refresher on the basics. If you're preparing for an introductory exam, building a small electronics project, or simply curious about how household wiring works, these questions will help you build a solid mental framework. The mix of definitions and short calculation prompts makes it easy to move from memorizing concepts to applying them.
Because much of this material builds on a small set of equations, try to focus on understanding the relationships rather than just memorizing formulas. When you review, work through the derivation cards alongside the definition cards so you can see how the same ideas appear in different contexts. Spacing your study sessions over several days is especially effective here, since repeated exposure helps the connections between Ohm's law, power, and Kirchhoff's laws become second nature.
