Network Analysis is the study of electrical circuits and their behavior under different conditions. It provides systematic methods to analyze voltage, current, power, and energy in electrical networks. The subject deals with basic circuit elements such as resistors, inductors, capacitors, voltage sources, and current sources. It introduces fundamental laws such as Ohm’s Law, Kirchhoff’s Current Law (KCL), and Kirchhoff’s Voltage Law (KVL). Important network theorems such as Superposition, Thevenin’s, Norton’s, and Maximum Power Transfer are used to simplify circuit analysis. It also covers AC circuit analysis using phasors and complex numbers. Students learn transient and steady-state responses of electrical circuits, along with resonance, two-port networks, and network functions. Network Analysis forms a foundation for subjects such as Signals and Systems, Control Systems, DSP, and Communication Engineering. The subject helps students develop analytical and problem-solving skills for practical circuit design and troubleshooting.
