Vpp is Peak-to-Peak voltage, in other words, in AC voltage, the peak-to-peak voltage is the potential difference between the lowest trough in the AC signal to the highest. Assuming the reference to the voltage is zero, Vpp would be twice the peak voltage (between zero and either the highest or lowest point in the AC waveform).
Vrms is the Root Mean Square voltage, think of it as sort of an average (it's not quite that simple). For a sine wave, the RMS voltage can be calculated by
y=a*sin(2ft)
where f is the frequency of the signal, t is time, and a is the amplitude or peak value.

What is the formula for ripple voltage in current?
V(ripple)= V(rms) / V (DC)
Is utility voltage ie 110 VAC given as a RMS value or as a Peak value?
All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.
The rms value of sinusoidal 200v peak to peak wave is?
You can work this out yourself. For a sinusoidal waveform the rms value is 0.707 times the peak value. As you quote a peak-to-peak value, this must be halved, first. Incidentally, the symbol for volt is 'V', not 'v'.
How do you change dc values to ac values?
To convert DC values to AC values if you are wanting RMS values they are the same. 100V DC and 100V AC (RMS) are the same "value". If you want to know the Peak-To-Peak AC value you would multiply the RMS value by 1.414. So 100V AC RMS equals 141.4 V Peak to Peak.
Is AC voltage measured from Peak to Peak or from 0 to peak?
Both. When an AC voltage is measured and a number is reported, it is necessary to state that this number is rms value or peak value or peak to peak value.AnswerVoltages and currents are each normally expressed in root-mean-square (rms), unless otherwise stated. For example, when we talk about a '120-V service' or a '240-V service', we are expressing the voltages in rms values; it is unecessary to specify that these are rms values. For a sinusoidal waveform, Vrms = 0.707 Vpeak
What is the rms current for an 8.0 µF capacitor attached to a 120 V rms 60 Hz source?
The RMS current for an 8.0 µF capacitor attached to a 120 V rms 60 Hz source is 39,798 amperes.
What is the formula for ripple voltage in current?
V(ripple)= V(rms) / V (DC)
If we have 100A than who much kva?
100 A (rms) x 240 V (rms) = 24000 VA = 24k VA
How do you convert vrms to vpp?
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
When was VPP developed by OSHA?
1982The VPP was created in 1982.
When was the VPP established?
By a site participating in VPP, incident rates are at least below the industry average
What is the fullform of VPP?
The full form of VPP is "Value Payable Post"
The fundamental premise of vpp is that it is a?
VPP attempts to support a culture change supportive of safety in the workplace.
How many volts an amps would it take to power a 120 horsepower motor?
Since 1 HP=745.7W, 120 HP=89484W. If you're using DC, then your volt amp combination must satisfy the equation: 89484W=V*I. If you're using AC, then you must satisfy the equation: P=|V|*|I|*cos(ang(V)-ang(I)) P is average power, also known as real power. You want this value to be 89484W |V| is the voltage magnitude in rms (rms is what measuring equipment shows. US residential homes normally have 120V rms) (rms=root mean squared) |I| is the current magnitude in rms ang(V) is the phasor angle of the voltage ang(I) is the phasor angle of the current
Is utility voltage ie 110 VAC given as a RMS value or as a Peak value?
All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.
What year was vpp developed by osha?
Yes. VPP stands for Voluntary Protection Programs. VPP was developed by OSHA and is a cooperative program between management, labor, and OSHA.
What is voltage rms in relation to alternate voltage?
RMS voltage is the DC equivalent of your AC waveform. Vrms=(Vpeak)/(root two) If your peak voltage is 170V then the RMS voltage would be approx. 120 V (see related link)
