This course introduces the fundamental principles that govern electrical circuits. Students will explore both analog and digital circuit behavior, learning to analyze and design systems using key concepts such as Ohm's law, Kirchhoff's laws, Network theories, and signal processing techniques. Through a combination of theoretical instruction and hands-on laboratory work, students will develop practical skills in circuit modeling, simulation, and measurement. Topics include RLC networks, Thevenin and Norton equivalents, Nodal and Mesh analysis, filters, and power supplies.
