This course aims to provide a basic understanding of the behaviour of electrical circuits containing inductance, capacitance and resistance when ac and transient dc signals are applied to them. It also develops measurement, analysis and reporting skills in the laboratory.

By the end of this course students will be able to:

■ state the basic properties of resistors, capacitor and inductors, and deduce their behaviour at dc steady state and to sudden changes;

■ apply a standard approach to solving problems in the context of electrical circuits;

■ explain the significance of the initial conditions in transient analysis and determine the initial conditions for first and second-order circuits switched between two steady DC states;

■ use differential equations to analyse the response to transient dc sources of first-order electrical circuits containing resistors and either capacitors or inductors;

■ use differential equations to analyse the response to transient dc sources of second-order electrical circuits, including series and parallel LCR circuits;

■ distinguish between underdamped, critically damped and overdamped response of RLC circuits;

■ calculate the impedance of circuits containing resistors, capacitors and inductors;

■ use impedance and standard methods of circuit analysis to calculate the behaviour of circuits driven by a steady ac source, with reference to phasor diagrams;

■ explain the concept of resonance;

Laboratory

■ demonstrate skill in the use of basic electrical test and measurement equipment including digital oscilloscope, function generator and multimeter;

■ deduce values of components in an RC circuit by measuring and analysing its transient response;

■ deduce values of components in an RLC circuit by measuring and analysing its transient response;

■ maintain a neat, complete laboratory record with analysis as the experiment proceeds.
