Abstract
Alternating current, or ac, theory is concerned with the mathematical analysis of the steady-state behaviour of electrical circuits in which the currents and voltages vary periodically with time. The analysis is simplified by considering only sinusoidal variations, an approach which is not restrictive since any general periodic waveform can be represented as a sum of such quantities, i.e. a Fourier series. In this chapter, it is shown how the sinusoidal waveforms can be represented both graphically and mathematically and how, in consequence, the effect of various circuit elements can be expressed in terms of generalized impedances.
