ELECTRIC CIRCUIT ANALYSIS
Basic Concepts: Active and passive elements, Concept of ideal and practical sources. Source transformation and Source shifting, Concept of Super-Mesh and Supernode analysis. Analysis of networks by (i) Network reduction method including star-delta transformation, (ii) Mesh and Node voltage methods for ac and DC circuits with independent and dependent sources. Duality
Network Theorems: Super Position theorem, Reciprocity theorem, Thevenin’s theorem, Norton’s theorem, Maximum power transfer theorem and Millman’s theorem. Analysis of networks, with and without dependent ac and DC sources.
Resonant Circuits: Analysis of simple series RLC and parallel RLC circuits under resonances. Problems on Resonant frequency, Bandwidth and Quality factor at resonance
Transient Analysis: Transient analysis of RL and RC circuits under DC excitations: Behavior of circuit elements under switching action, Evaluation of initial conditions.
Laplace Transformation: Laplace transformation (LT), LT of Impulse, Step, Ramp, Sinusoidal signals and shifted functions. Waveform synthesis. Initial and Final value theorems.
Unbalanced Three Phase Systems: Analysis of three phase systems, calculation of real and reactive Powers by direct application of mesh and nodal analysis.
