The Electrical Circuit Analysis lab encompasses a variety of experiments to deepen students’ understanding of fundamental theorems and circuit behaviour. Superposition theorem verification involves analyzing circuits with multiple sources by isolating each source’s effect individually and then combining the results. Thevenin’s and Norton’s theorem verification focuses on simplifying complex circuits into equivalent circuits, aiding in circuit analysis and design. The maximum power transfer theorem is explored to determine the load impedance for maximum power transfer from a source.

Frequency response analysis of series and parallel RLC circuits helps students understand how these circuits behave at different frequencies, including resonance and bandwidth characteristics. Measurement of steady-state and transient responses of RL, RC, and RLC circuits provides insights into circuit dynamics under various conditions.

Z and H parameter analysis of two-port networks in DC conditions helps students characterize network behavior in terms of impedance and hybrid parameters, aiding in network analysis and design. Determining driving point and transfer functions of a two-port ladder network allows students to verify theoretical values through practical experimentation.

Characteristics impedance analysis of T and Pi networks helps students understand impedance matching and transmission line behavior. Interconnecting two-port networks in series and parallel further enhances students’ understanding of network configurations and their combined effects.

Lastly, studying the frequency response of a Twin T notch filter and active filter provides hands-on experience in designing and analyzing filter circuits for signal processing applications, bridging theoretical concepts with real-world applications in circuit design and analysis.
