Learning Outcomes

Circuit Theory • Electric current, potential difference, EMF’s, resistors, ohms law, power • Circuits with one EMF - Kirchhoff’s laws, resistors in series and parallel, potential dividers, internal resistance of batteries • Measuring current and potential difference – digital multimeters and other tools • Measuring resistance a) by measuring V and I, and b) with a Wheatstone Bridge • Multi-loop networks with more than one EMF – branch and loop currents, generating and solving simultaneous equations by applying Kirchhoff’s voltage law. Superposition. • Capacitors as circuit elements, energy stored in a capacitor, series and parallel connection. • Inductors as circuit elements – basic construction and electrical properties, energy stored in an inductor. • Transient response (Charge and discharge) of capacitors. Step and pulse response of C-R circuits • Transient response of R-L. • Kirchhoff’s laws applied to Bridge circuits • Circuit simplification by utilising Thevenin’s theorem Electronics •Introduction– analogue and digital electronic systems •Examples of digital electronics (switching and control systems, computers, digital signal processing) • Combinational logic circuits –one and two input gates, Boolean algebra, deMorgan's law. • Analysis and design of combinational logic circuits, simplification using Karnaugh maps.
