A: Peak voltage is RMS multiplied by a factor of 1.41
The peak voltage is 1.414 times the rms.
RMS means root mean square of a sinusoidal wave form and the number that describe it is .741 of the peak average is ,639 of the peak
Following is the Voltage calculation for a 3 Phase Full wave rectifier bridge circuit with 6 diodes: Vac rms (Ph-Ph input) = 2pi / 3√2 x Vdc (output) Vac rms (Ph-Ph input) = 0.74 x Vdc (output) Hope that helps :) Regards, Syed
It is the 'as if' voltage in an AC circuit. Referred to as Vrms 120 volts in your house is Vrms, the effective voltage, 'as if' it were DC 120V, can do the same work. But 120VACrms is a sine wave with a peak voltage much higher than 120 volts.
For a sine wave, the form factor is the square root of 2. Thus, the effective voltage of 56 V (56 Vrms) is 2-1/2 times the peak-to-peak voltage. Thus, the peak-to-peak voltage Vpp = Vrms * sqrt(2)In this example:Vpp = 56V * 1.4142... = 79.2V (rounded to one decimal place)
the answer is 5.6vp-p
To conver Vrms in to Voltage Source we useVm=√2 (vi)
RMS means root mean square of a sinusoidal wave form and the number that describe it is .741 of the peak average is ,639 of the peak
piv:the maximum value of reverse voltage across a diode that occurs at the peak of the input cycle when the diode is reversed-biased.
Many can measure both - Vrms (AC) or DC voltage.
Vrms=Vm/1.414................... from this u can find Vm.....magnitude of voltage.
Approx. 280 VRMS. Vpeak * 0.707 = Vrms

Vrms = Vpp/squareroot(2)This can be written another way:Vrms * squareroot(2) = VppAnswerThe question asks for the relationship between the rms value of voltage, and the peak-to-peak value of voltage, not the peak value (Vmax) of voltage, so:Vp-p = 2 Vmax = 2(1.414) Vrms = 2.828 Vrms

Vrms=1.414xVpk to pk
Assuming sine wave (it is different if not): Vp-p = 2.828 * Vrms
