Assume that the AC generator has a sine wave output across its terminals A and B. The peak value of the output voltage is 100V. AC GENERATOR Figure 13-1. a. On the graph of Figure 13-2, draw the sine wave output voltage of the generator. Plot your voltage points at 15° intervals (starting from 0° to 360°). b. Draw a smooth curve through all of your plotted points and label this voltage curve "e". Note: The abbreviations for instantaneous voltage are "e" and "vas opposed to the conventional "E" and "V".
