current and voltage, it is often necessary to express the
current and voltage in terms of MAXIMUM or PEAK values, PEAKto
values. Each of these values has a different meaning and is
used to describe a different amount of current or voltage.
(1) PEAK And PEAKTOPEAK Values. Refer to figure 64 on the
following page. Notice it shows the positive alternation of a
sine wave (a halfcycle of ac) and a dc waveform that occur
simultaneously. Note that the do starts and stops at the same
moment as does the positive alternation, and that both waveforms
rise to the same maximum value. However, the dc values are
greater than the corresponding ac values at all points except
the point at which the positive alternation passes through its
maximum value. At this point the dc and ac values are equal.
his point on he ine wave is referred to as the maximum o
