Top Answer

rms voltage is a 'root mean square' voltage. This is used because every second amplitude of the voltage keeps varing between various peaks. Sometimes we also do refer to peak voltage also.

A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41

The average voltage is the rms voltage.Volts peak = volts RMS times 1.414Volts RMS = volts peak times 0.7071Use the link below to an RMS voltage, peak voltage and peak-to-peak voltage calculator.********************************The average voltage is not the r.m.s. voltage.The average voltage of a sine wave is 0.636 x the peak value. Conversely, peak voltage is 1.57 the mean or average.

rms stands for root mean squared. rms voltage is a way of measuring a sort of average alterating current voltage as distinguished from peak-to-peak voltage. Likewise for ac rms current.

If voltage is given as RMS voltage (which it normally is), simply multiply the number of volts by the RMS current (as number of amps), and then divide by one thousand. Power (in kW)=Voltage (RMS volts) * Current (RMS amps) / 1000 (watts/kW)

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)

In a standard sine-wave the peak voltage is sqrt(2) times the rms.

When people talk about 480V systems, they mean 480 is the RMS voltage.

RMS = root mean square. The RMS of an AC voltage is VAC / sqrt(2) where VAC is the voltage peak to neutral. typical home voltage is 110 - 120volts RMS, if you took an oscilloscope and looked at it, you'd notice the voltage peak is closer to 170 volts.

1.414 * RMS voltage

That is an electric AC or audio output, where the voltage is measured in volts rms. Scroll down to related links and look for "dB conversion (decibel)". Look there in the middle at this headline: "RMS voltage, peak voltage and peak-to-peak voltage".

Peak voltage will be 1.414 times the RMS. Peak to Peak voltage, assuming no DC offset, will be 2 x 1.414 x the RMS value.

RMS to peak, times 1.414. Peak to RMS times .707.

Conversions of RMS voltage, peak voltage and peak-to-peak voltage. Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".

To answer the exact question, 220 Volts RMS is the voltage of a supply of electric power which is twice as big as 110 Volts RMS. Note: ordinary electrical test meters (multimeters) normally measure the RMS value, not the peak value, when they are used to measure an amount of AC voltage or current. Scroll down to related links and look at "Difference between RMS voltage, peak voltage, and peak-to-peak voltage". Further notes: RMS is an acronym for 'Root Mean Square'. In essence, it's an overall average voltage rating which tells you the 'real work' which can be done by a supply of power, or, in other words, it is a truer representation of the overall power profile delivered over time by an alternating voltage supply.To determine an RMS voltage of a sine wave (as is used in AC mains power distribution), you measure its peak voltage and multiply it by .707, which will give you the RMS voltage.So a 110 Volt RMS mains supply actually has a peak voltage of about 155.6 Volts and a 220 Volts RMS mains supply actually has a peak voltage of about 311.2 Volts.

TO BE SPECIFIC --- RMS VOLTAGE ONLY Note to orignal answerer: RMS voltage is not the only voltage form that can be measured. Depending on the design a Voltmeter can give an output in terms of peak to peak voltage and also can be used to measure a DC voltage, both of which are very different measurements to an RMS voltage

RMS stands for Root Mean Squared. It is this average voltage that is read on a multimeter.

To calculate the peak voltage of an RMS voltage in a sine wave simply multiply the RMS voltage with the square root of 2 (aprox. 1,414) like this: 240 x 1,414 = 339,4 V RMS x sqr.root of 2 = peak voltage

Conversions of RMS voltage, peak voltage and peak-to-peak voltage. That are the used voltages. The expression "average" voltage is used for RMS voltage.Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".Answer'Average' is not the same as 'root mean square'. As the average value of a sinusoidal voltage is zero, you cannot convert it to a peak-to-peak value.

Peak to peak voltage is the voltage differential between highest and lowest voltages in a waveform. In a typical AC (sinusoidal) waveform of 117 volts, the peak to peak voltage would be about 165 volts. RMS voltage is the average value, specifically the Root Mean Squared voltage. RMS voltage for a sinusoidal waveform is peak to peak voltage divided by the square root of two. The conversions for other wavforms, such as triangle, are different. In essence, the RMS voltage is the square root of the limit of the sum of the squares of the voltages divided by N, where N approaches infinity. Root of the Mean of the Square. In the extreme case of a square wave, RMS voltage and peak to peak voltage are the same. The RMS value is used because it more correctly describes the available average power in a varying voltage or current source. When stating an AC voltage, RMS is implied, unless some other method is stated, i.e. 120VAC means 120VAC-RMS.

You don't need to convert an rms value of voltage to find the DC equivalent -it is the DC equivalent! 120 V (rms) is exactly equivalent to 120 V DC.Going back to basics, the rms value of an alternating current is equivalent to the value of a direct current. For example, 10 A (rms) will do precisely the same amount of work as 10 A DC. Since voltage and current are proportional (Ohm's Law), then the same applies to a voltage.

From Wikipedia:"In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids."Since AC voltage is a sinusoid, the RMS voltage is one measure of the amount of voltage. It is also measured as a peak-to-peak value. Since Current = Voltage divided by Resistance, the same RMS measurement approach applies.

I am not certain what is being asked here. RMS is Root Mean Square which is basically the DC voltage which would produce the same amount of heat in a heating element as the AC voltage in question. Since AC is continuously changing in polarity and voltage, it is handy to use the RMS voltage rather than the peak (169.7V for 120V RMS) or peak-to-peak (339.4V for 120V RMS). The peak or peak-to-peak voltage is handy to know when considering the maximum values such as in rectification.

No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.
