Not all the quantites,but Most of the quantities in electrical system are varying in nature.RMS can mainly measure the magnitude of the quantities that are varying in nature.
Mathematically speaking it can be calculated for a series of discrete values or for a continuously varying function.
AnswerAn r.m.s. value is the value of an a.c. current that performs exactly the same amount of work as a given value of d.c. current. In other words, 10 A (r.m.s.) does exactly the same amount of work as 10 A (d.c.). Since voltage and current are proportional, it also applies to voltage. So, it provides a way of comparing a.c. values with d.c. values.

rms. dat means Vp-p will be 325V.
All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.
When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
A square wave has the highest RMS value. RMS value is simply root-mean-square, and since the square wave spends all of its time at one or the other peak value, then the RMS value is simply the peak value. If you want to quantify the RMS value of other waveforms, then you need to take the RMS of a series of equally spaced samples. You can use calculus to do this, or, for certain waveforms, you can use Cartwright, Kenneth V. 2007. In summary, the RMS value of a square wave of peak value a is a; the RMS value of a sine wave of peak value a is a divided by square root of 2; and the RMS value of a sawtooth wave of peak value a is a divided by cube root of 3; so, in order of decreasing RMS value, you have the square wave, the sine wave, and the sawtooth wave.

rms value is measured using voltmeter with the use of heat sensing elements.
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.
AC RMS Value x 1.414
You don't need exactly one cycle data for computing the RMS value. It is just a convenient normalization. 1 cycle = 1Hz. RMS values can also be specified in 1 Mcycle, 1kcycle, even 2.39384kcycles. Again, 1 cycle is simply convenient. In other words, if the RMS value were specified in MHz, the RMS value will be 20*log(MHz/Hz) higher.
Its 0.7 times peak-0 voltage, 106 mv RMS.
RMS is just 15/sqr2 average is 15 * 0.637
