I think it's peak or peak to peak.

In ac circuit there is a voltage is display on voltmeter rms(root mean square). It shows the equal values of dc and ac sources.

Voltage to be measure is in rms peak to peak consider in calculation.

This is true only if the meter is a true RMS meter, otherwise this is false.

A.C meters in R.M.S ------- voltage,current
D.C meters in AVG ----- voltage and current
But power is AVG value in A.C AND D.C.
