peak-to-peak (pk-pk)

Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum negative amplitudes of a waveform, as shown below. If there is no direct current ( DC ) component in an alternating current ( AC ) wave, then the pk-pk amplitude is twice the peak amplitude.

For an AC sine wave with no DC component, the peak-to-peak amplitude is equal to approximately 2.828 times the root-mean-square amplitude. Peak-to-peak values can be expressed for voltage (the usual case), current , or power .

"If there is no direct current ( DC ) component in an alternating current ( AC ) wave, then the pk-pk amplitude is twice the peak amplitude."

"For an AC sine wave with no DC component, the peak-to-peak amplitude is equal to approximately 2.828 times the root-mean-square amplitude."

So which is it

Both.( (Voltage x 2) x 1.414) is the same as saying (Voltage x 2.828). 1.414 x 2=2.828. Work e problem both ways and you will see it comes out the same. The "DC component" part can be ignored for now because a "DC component" would be a relatively flat wave form either positive or negative. The text is focusing on an AC wave form. Hope this helps.
