Description: Aims:
The aim of this unit is to provide an introduction to electronics by developing an understanding of basic concepts in dc and ac electric circuits, as relevant to laboratory work in physics.

Learning Outcomes:
After taking this unit the student should be able to:
* use systematic analysis methods to calculate currents and voltages in passive dc circuits;
* calculate the amplitude and phase of voltages and currents in ac circuits by means of phasor analysis;
* analyse simple operational amplifier circuits from first principles;
* qualitatively describe both transient and steady-state responses of simple LCR circuits.

Skills:
Numeracy T/F A, Problem Solving T/F A.

Content:
DC circuits ( 4 hours): Kirchoff's voltage and current laws. Ideal voltage and current sources. Analysis of simple circuits using nodal voltage technique. Impedance matching; input/output impedance, maximum power transfer.
AC circuits ( 5 hours): AC voltage and current concepts (phase, rms value, amplitude, etc.). Capacitors and inductors as circuit elements. Phasors and phasor notation. Complex impedance. LCR circuits (resonance, Q factor, etc). Frequency dependence of circuits.
Ideal operational amplifiers ( 1 hour): Simple applications.
Transients (1 hour): Transient waveforms in simple circuits involving inductors, capacitors and resistors.
