### Syllabus

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 – moving coil meters, shunts and multipliers; digital voltmeters and ammeters. • 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 • Digital Electronics o Examples of digital electronics (switching and control systems, computers, digital signal processing) o Combinational logic circuits –one and two input gates, Boolean algebra, o Analysis and design of combinational logic circuits, simplification using Karnaugh maps. Circuits with NAND gates only. o Sequential logic circuits – flip-flops, counters, shift registers. • Analogue Electronics o Properties of operational amplifiers o Op-amps as comparators – sine to square converter, generation of variable width pulses from a triangle waveform o Op-amps with negative feedback – inverting and non-inverting amplifiers, voltage follower, inverting summing amplifier, difference amplifier, differentiator and integrator AC Circuit Theory • AC voltage sources, amplitude and phase of voltage across R L and C driven by an AC current source. RMS values. • AC networks – phasors and their application (high and low pass filters).
