 ## Electric Circuit Analysis

Semester 1

This course introduces students to the fundamental building blocks of electrical and electronic circuit theory. The basic electrical circuit tools required to analyze the characteristics, the behaviour, functionality and performance characteristics of electrical circuits containing resistors, inductors and capacitors are introduced. These tools are applied to obtain both the full dynamic performance of circuits and the steady state performance of sinusoidal systems.

Syllabus:
• Concepts in basic electrical quantities: electronic charge, current, voltage, power, energy
• Introduction to circuit theory
• Simple circuits
• Kirchhoff’s voltage and current laws
• Series and parallel circuit networks
• Structured Circuit Theory
• Network theorems: Superposition, Thevenin’s, Norton’s
• Solution using structured approach
