Answer:
draw the waveform of alternating current and direct current and explain the magnitude time curve
Answer:
When an alternator produces AC voltage, the voltage switches polarity over time, but does so in a very particular manner. When graphed over time, the "wave" traced by this voltage of alternating polarity from an alternator takes on a distinct shape, known as a sine wave: Figure below .
Graph of AC voltage over time (the sine wave).

In the voltage plot from an electromechanical , the change from one polarity to the other is a smooth one, the voltage level changing most rapidly at the zero ("crossover") point and most slowly at its peak. If we were to graph the trigonometric function of "sine" over a horizontal range of O to 360 degrees, we would find the exact same pattern as in the Table below.
