Linear Circuit Analysis (Th.) | (ET-124) | (Section B)

Linear Circuit Analysis is the first course of the three-course sequence covering the Electric Circuits and Electronics stream.

First portion of this course introduces concepts of charge, current, and voltage to be followed with the description of current and voltage sources. An introduction to networks and circuits is accompanied by a detailed discussion of Ohm’s law and Kirchhoff’s laws. This is followed by circuit analysis techniques using Nodal and Mesh Analysis with particular reference to super-node and super-mesh. A comparison of Nodal and Mesh analysis is also made. The first portion will also cover the Circuit Analysis Techniques including linearity and superposition, source transformations; important theorems like Thevenin’s, Norton’s, reciprocity theorem, and Maximum Power Transfer Theorem. The circuit reduction techniques covering Delta-Wye conversion are also covered to allow the students to analyze the simplified circuits.

Second Portion of this Course will introduce capacitance, inductance and their series and parallel combination. First-order RL, RC Circuits, and second-order RLC circuits are also taught to find the transient and steady-state response of these kinds of circuits.

Third portion of this course introduces AC fundamentals, Periodic function, RMS, effective, average, and maximum values of current and voltage for periodic waveforms, the study of simple circuits using instantaneous values of current and voltages, introduction to the three-phase system. Phasor Quantities, the complex expression for current, voltage, and impedance.
