A: Root Mean Suare and it is defined as .707 of the peak
What else can I help you with?
What do you mean by rms value of current and 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.
How to measure the root mean square value of MESURED voltAGE in convential voltmeter?
A conventional voltmeter displays 0.707 of the peak voltage when it measures AC.In doing so, it displays the RMS value of the measured voltage IF the measured voltage is a sinusoid.If the measured voltage is not a sinusoid, then its peak value is 1.414 times the displayed number, andyou have to calculate the RMS based on the waveform.
Is 240v rms value or peak value for AC source?
rms. dat means Vp-p will be 325V.
Household supply of 230volts is rms value or maximum value of voltage?
When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
Which has a higher RMS value given a sine wave a square wave and a sawtooth wave?
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.

How do you measure rms value of complex waveform?
rms value is measured using voltmeter with the use of heat sensing elements.
Does a volt meter read rms?
Yes, if it is set to measure AC, it is usually calibrated to RMS.
How to derive the RMS of a full wave rectifier?
AC RMS Value x 1.414
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.
Is a sinusoid a function whose value should repeat based on positions of a point that moves around a circle?
yes
Why do we need exactly one cycle data for computing the RMS value?
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.
Find rms and average value of 15a current?
RMS is just 15/sqr2 average is 15 * 0.637
