Description:  Aims: The aim of this unit is to provide a preparation for work in the undergraduate physics laboratory by discussing dimensions and units, developing an understanding of basic concepts in dc and ac electric circuits, and introducing basic ideas of error analysis, statistics and probability relevant to the understanding and interpretation of experimental data. Learning Outcomes: After taking this unit the student should be able to: * apply dimensional analysis to expressions linking measurable variables; * use a systematic analysis method 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; * apply the propagation of errors formula; * evaluate the standard error on a mean of experimental measurements; * apply leastsquares fitting to experimental data; * write down expressions for the fundamental probability distributions and apply them appropriately.
