How this course works
Practice · open
Practice sheets: any help allowed, AI included
Each chapter has a practice sheet you can solve online, with instant feedback, or print. Practice sheets are not marked for correctness. Use your notes, classmates or an AI tool, but check every AI answer: chatbots often get signs and directions wrong.
In class · device-free
Quizzes and quick oral checks
Each chapter has a short quiz in class, without phones or laptops, and any student may be asked to explain a step out loud. Every quiz question is a twin of a practice-sheet question: the same idea with new numbers or orientation. If you can do the sheet on your own, you will do well on the quiz.

Course learning outcomes
- CLO1Use Ohm’s law, Kirchhoff’s laws, voltage division and current division in circuit analysis.
- CLO2Use node-voltage and mesh-current methods, source transformation, Thévenin and Norton equivalent in circuit analysis.
- CLO3Analyze simple ideal op amp circuits.
