Aims

This module will introduce the fundamental theorems and analysis techniques for problem-solving in electrical circuit theory. This unit provides students with the knowledge and intellectual skills necessary to model and analyse circuits in a wider electrical engineering and electronics context. This unit used to develop practical and written skills by providing laboratory experiments.

Learning Outcomes

1.
Apply AC and DC circuit theory to solve series and parallel R-L-C circuits and apply complex wave to explain the basics of R-L-C circuits.
2.
Identify two port network model to evaluate the basic electrical circuits and system include R-C, R- L Filter circuits and network.
3.
Contrast transient behaviour of switched circuits with first, second and higher orders.
4.
Apply DC and AC circuits in the laboratory with the use of computer simulation software and laboratory equipment's.

Module Content

Outline Syllabus:Circuit theorems: Norton; Kirchhoff; Thevenin; superposition; maximum power. Circuit analysis: mesh; nodal; maximum power transfer; impedance matching. Phasor diagram to analyse the single phase circuits. Complex notation in the analysis of single phase circuits. Circuit performance: tolerance; effect of changes in component values Two-port network models Network models: symmetrical two-port network model; characteristic impedance, Zo; propagation coefficient (expressed in terms of attenuation, α, and phase change ß); input impedance for various load conditions including ZL = Zo; relationship between the neper and the dB; insertion loss Symmetrical attenuators: T and π attenuators; the expressions for Ro and α in term of component values Transients in R-L-C circuits Laplace transforms: definition of the Laplace transform of a function; use of a table of Laplace transforms Transient analysis: expressions for component and circuit impedance in the s-plane; first order systems must be solved by Laplace (i.e. RL and RC networks); second order systems could be solved by Laplace or computer-based packages. Circuit responses: over, under, zero and critically damped response following a step input; zero initial conditions being assumed. Properties: power factor; RMS value of complex periodic waveforms Fourier coefficients of a complex periodic voltage waveform such as Fourier series for rectangular, triangular or half-wave rectified waveform, use of a tabular method for determining the Fourier series for a complex periodic waveform; use of a waveform analyser; use of an appropriate software package. Use of software package (such as OrCAD/pspise or similar industrial based software) to simulate the basic R-C, R-L and R-L-C circuit and analyse the circuit performance by measuring current voltage and power for DC/AC circuits. Design and demonstrate basic R-C, R-L and R-L-C circuit in the laboratory and analyse the circuit performance by using signal generator, oscilloscope and multimeters.
