When a digital multimeter is used to measure the AC voltage, does it show the amplitude of voltage or peak-to-peak voltage ?
 

hi,
Most AC meters are scaled in RMS, which is 0.707 * Vpeak.

hi,
it shows nor amplitude, nor p-p value .It shows by calibration the effective value which is 0.707 of peak value like esp1 says.
Peak value is then greater from efecive value by sqrt(2)
