In this chapter you will learn how to: understand and use the terms period, frequency and peak value as applied to an alternating current or voltage use equations of the form x = x0 sin ωt representing a sinusoidally alternating current or voltage recall and use the fact that the mean power in a resistive load is half the maximum power for a sinusoidal alternating current distinguish between root-mean-square (r.m.s.) and peak values and recall and use and for a sinusoidal alternating current distinguish graphically between half-wave and full-wave rectification explain the use of a single diode for the half-wave rectification of an alternating current explain the use of four diodes (bridge rectifier) for the full-wave rectification of an alternating current analyse the effect of a single capacitor in smoothing, including the effect of the value of capacitance and the load resistance.
