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
