AC GENERATION ANALYSIS Basic AC TheoryAC GENERATION ANALYSISAnalysis of the AC power generation process and of the alternating current we usein almost every aspect of our lives is necessary to better understand how ACpower is used in today’s technology.EO 1.3 DEFINE the following terms in relation to ACgeneration:a. Radians/secondb. Hertzc. PeriodEO 1.4 DEFINE effective value of an AC current relative to DCcurrent.EO 1.5 Given a maximum value, CALCULATE the effective(RMS) and average values of AC voltage.EO 1.6 Given a diagram of two sine waves, DESCRIBE thephase relationship between the two waves.EffectiveValuesThe output voltage of an AC generator can be expressed in two ways. One is graphically by useof a sine wave (Figure 3). The second way is algebraically by the equatione = Emax sin wt, which will be covered later in the text.Figure 3 Voltage Sine WaveES-07 Page 4 Rev. 0
