If by RMS voltages you mean what is the RMS voltage of the power source voltage to the device proper it might be 120 volts AC like right out of the wall where you plug it in. That 120 VAC is an RMS voltage. That's the way we measure AC voltages like those wired into residential and commercial settings. Picture an AC sine wave. For a sine wave that is 120 volts RMS, its peak voltage will be right at about 170 volts. Volts RMS is the so-called DC equivalent voltage. The RMS voltage for a larger X-ray machine could be 220 VAC or 440 VAC, too, as higher power units are available. These units can be fixed or "permanent" in a medical setting or in an industrial plant, and can take advantage of higher electrical bus voltages. The X-ray tube itself runs on a DC voltage. A DC voltage doesn't usually have the idea of RMS associated with it. The voltage is "fixed" and not changing over time like it does in an AC source. Modern X-ray tubes can have operating voltages that range from 10 kV to 300 kV applied to accelerate the electrons before slamming them into an anode target.

What is RMS in electricity?
RMS stands for Root Mean Square. Power is calculated as V2/R where V is the voltage and R is the resistive component of a load, This is easy toi calculate for a DC voltage, but how to calculate it for a sinusoidal voltage? The answer is to take all the instantaneous voltages in the sine wave, square them, take the mean of the squares, then take the square root of the result. This is defined as the "heating effect voltage". For a sine wave, this is 0.707 of the peak voltage.
Was the Titanic SS or RMS?
RMS
When was the RMS Titanic completed?
The RMS Titanic was completed March 31, 1912.
What ship came to help the survivors of the titanic?
The RMS Carpathia was the one who rescued the survivors
When did Musicians of the RMS Titanic die?
Musicians of the RMS Titanic died on 1912-04-15.
Why you need for true RMS multimeter?
RMS mean root mean square not all voltages are pure sine waves so the true RMS can be found by using this type of meter.
Can airport xray machines see diamonds?
Yes an airport xray will pick up a diamond or multiple. ( source airport worker )
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.
If The wall outlet has RMS value of 120VAC what is the peak value?
220 V is rms in europe if that is what you are getting at. Peak is at about 311 V.AnswerUnless otherwise stated, all a.c. voltages and currents are expressed in r.m.s. values.
What can't xray machines see through?
X-ray machine can't see though led
What is meaning rms?
In shipping it meant Royal Mail Ship, as in RMS Titanic. There are most likely a lot of other meanings also.
What steps does it take to get a job in radiology?
"You must first complete a 2 year program in medical disciplines including certifications in the use of radiologic equipment such as XRay machines, MRI machines and CT scan machines."
What is the effective voltage for 3 phase 220 VAC power?
If, by 'effective' voltage, you mean 'root-mean-square' (rms) voltage, then 220 V is already expressed in those terms.Unless otherwise stated, a.c. voltages and currents are always expressed in rms values.
Does airport xray machines damage digital camcorders?
If in doubt, take it by hand. Pass the digital picture frame to security and be prepared to show them that it really is just a picture frame
What happen when 220v ac lamp connected to220v dc?
All a.c. voltages and currents are expressed in root-mean-square (rms) values. An rms voltage of 220 V is exactly equivalent to a d.c. voltage of 220 V. So the lamp will function quite normally at either voltage.
How do you calculate the RMS of 440volts 220 volts 110 volts?
RMS stands for root mean squared, and is an easier way to refer to AC voltage. To calculate Vrms, you just take your peak voltage and divide by the square root of 2. Thus, we get the equation Vp/(2^1/2). For power and amperage the calculation is a bit more complicated, but it's very easy for voltage. Therefore your answers, assuming that your given voltages are the peak voltages of the sinusoid, will be 311.12v, 155.56v and 77.78v respectively. If you want to go from the RMS value to the peak value, simply multiply by the square root of two.
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
