Circuits & Networks (PCEET302) Syllabus

Mesh analysis and nodal analysis (review only), super mesh and super node, superposition principle, source transformation, analysis with DC and AC (sinusoidal) excitation. Thevenin's theorem, Norton's theorem, maximum power transfer theorem — analysis with DC and AC (sinusoidal) excitation with independent and dependent sources. Reciprocity theorem — application to the analysis of DC circuits.

Resonance — series resonance, resonant frequency, variations of impedance and current with frequency, bandwidth, quality factor, parallel resonance (series RL in parallel with C — calculation of resonant frequency). Power in 3-phase circuits — complex power, active/reactive/apparent power in balanced load, steady-state analysis of 3-wire unbalanced delta connected circuit, steady-state analysis of 3-phase 4-wire and 3-wire (using Millman's theorem only) unbalanced star connected circuit, neutral shift.

Laplace transforms (review only). Transient response of simple series and parallel RL and RC circuits with DC excitation and initial conditions — natural response and forced response, time constant, solution using Laplace transforms, transformed circuits in s-domain, solution using mesh analysis and nodal analysis. Transient response of series RLC circuit with DC excitation and initial conditions — damping (overdamped, underdamped, critically damped and undamped), solution using Laplace transforms. Transient response of simple series and parallel RL and RC circuits with sinusoidal excitation and zero initial conditions — solution using Laplace transforms.

Two port networks — Z, Y, h, T parameters, conditions for symmetry and reciprocity, relationship between parameters, interconnection of two port networks (series, parallel and cascade). Coupled circuit — dot convention, fixing of dots, coefficient of coupling, conductively coupled equivalent circuit, sinusoidal steady state analysis of coupled circuits.
