question is not clear. RMS is .707 of peak. If you're asking about sums of currents or voltages represented by sine waves and they don't have the same frequency then the sum's RMS value is the square root of the sum of the squared amplitudes of the two waves. The squared amplitudes are proportional to the power in each current or voltage and the result represents the sum of the powers.
If the two sine waves have the same frequency then the sum's RMS value is the sum of the two RMS values. The physical circuit has to add power to the signal. (if the amplitudes are equal the resultant will have 4 times the power)

What will be the Flowchart for adding all elements in an array in c plus plus?
It is not possible to show a flowchart in this website -- it is text only. The algorithm can be summarised as follows: int sum(std::array<int>& a) { int sum = 0; // initialise the return value for (auto i : a) // for each value in the array sum += i; // increment the sum by the value return sum; // return the sum }

Why fourier series is used for frequency domain?
The fourier series relates the waveform of a periodic signal, in the time-domain, to its component sine/cosine frequency components in the frequency-domain. You can represent any periodic waverform as the infinite sum of sine waves. For instance, a square wave is the infinite sum of k * sin(k theta) / k, for all odd k, 1 to infinity. Using a Fourier Transformation, you take take a signal, convert it from time-domain to frequency-domain, apply some filtering or shifting, and convert it back to time-domain. Sometimes, this is easier than building an analog filter, even given that you need a digital signal processor to do it.

What is the relationship between peak to peak and peak voltage for a sine wave?
The RMS (root mean square) of the peak voltage of a sine wave is about 0.707 times the peak voltage. Recall that the sine wave represents a changing voltage, and it varies from zero to some positive peak, back to zero, and then down to some negative peak to complete the waveform. The root mean square (RMS) is the so-called "DC equivalent voltage" of the sine wave. The voltage of a sine wave varies as described, while the voltage of a DC source can be held at a constant. The "constant voltage" here, the DC equivalent, is the DC voltage that would have to be applied to a purely resistive load (like the heating element in a toaster, iron or a clothes dryer) to get the same effective heating as the AC voltage (the sine wave). Here's the equation: VoltsRMS = VoltsPeak x 0.707 The 0.707 is half the square root of 2. It's actually about 0.70710678 or so.

What is the average value of a pure sine wave?
The average value of a sine wave is 0. That's by integrating the function over a whole (or any integer number of whole-) cycles and dividing by the total time, n*T. In a "pure" sine wave, i.e., one with zero distortion, one half cycle has some total integral that's a sum of positive values, while the second half cycle is all *below the axis*, so negative in value and symmetrical with the first half. So when you add the two (or n*2) half cycles--which is integration--you get a sum of zero. No matter the frequency, or amplitude of the sine wave.
Write a program to find the sum of sine series?
Writing a program for a sum of sine series requires a rather long formula. That formula is: #include #include #include main() { int i,n,x; .
How do you determine an RMS value of a complex wave?
To explain the basics behind rms of complex waves and harmonics. Let V = Volt, I= Current, P = Average power, and rms or RMS as Route Mean Square (both are acceptable) and let e.m.f. be Electromotive Force. Then rms values for V or I can be obtained in the following manner. An electrical quantity such as V or I (be careful for P) in a pure sine wave will have a rms value of, lets use V as argument: Vrms = Vpeak/sqr(2) This mean that the rms is the average of the absolute value of the sine wave. Not of the sine wave it self. The average value of a sine wave is 0. It's important to know it is the absolute value. If we say for the sake of simplicity: i = I x sin(a+b) then i2 = I2.sin2(a+b) Since the average value is the sine amplitude divided by sqr(2), it makes sense to say that: average of sine2 = 1/2 [the square root falls away (sqr(2)2 = 2)] Thus, sin2(a+b) will have an average value of a 1/2, it will always be 1/2 since a sine wave will always have a peak value of 1 and 12 = 1 so let us say: An e.m.f produce a fundamental and another two harmonics, an e.m.f will normally produce odd harmonics such as 1st, 3rd and 5th i = I1.sin(a+b1) + I3.sin(a+b3) + I5.sin(a+b5) +..... In.sin(a+bn) i2rms = (1/2*I12)+(1/2*I32)+(1/2*I52)+...+(1/2*In2) remove the power from i irms = sqr[(1/2*I12)+(1/2*I32)+(1/2*I52)+...+(1/2*In2)] remove 1/2 as common and the result will be: irms = sqr[{(I12)+(I32)+(I52)+...+(In2)}/2] Or what appears to be more conventional, remove 1/2 and apply Sqr(2) below the line then it looks more like rms calculation :) irms = sqr[(I12)+(I32)+(I52)+...+(In2)] /sqr(2) Just another tip: I and V are done exactly the same but power is differenent since sqr(2) x sqr(2) = 2 and not sqr(2) so just to keep it simple do it as Pavr=Irms x Vrms so fist find Irms and Vrms before power, there might be short cut once you know this well, but for now it's best to do it like this and not to confuse you. To determine reactances and impedances, it's best to calculate each harmonic separately like XL1 = 2 x (pi) x f1 x L XL3 = 2 x (pi) x f3 x L XL5 = 2 x (pi) x f5 x L Z1=sqr(R2+XL12) Z3=sqr(R2+XL32) Z5=sqr(R2+XL52) Power due to harmonic is Ph = Eh(rms) x Ih(rms) x cos(a) where a is the V-I phase shift Ptotal = sum(Ph1+Ph3+Ph5+...) Then power factor PF= Ptotal / [Eh(rms) x Ih(rms)] Resonance is still at Xc=XL but only with individual harmonics, such as Xc1=XL1;Xc3=XL3;...
Why sqare waves are called analog waves?
A square wave is a sum of an infinite number of sine waves (analogue). These sine waves consist of one wave called a FUNDAMENTAL, and all of the other waves are called HARMONICS. The fundamental is the same amplitude and frequency as the square wave. The harmonics are all odd, i.e. mathematically, the first harmonic (which is called the 3rd harmonic) is 1/3 the amplitude and 3 times the frequency of the fundamental. The next harmonic (called the 5th harmonic) is 1/5 the amplitude and 5 times the frequency of the fundamental. And so it goes with the next harmonic (the 7th), followed by the 9th and so on ad infinitum.
What is meant by superposition of waves?
Superposition of waves is the combination of two or more waves where their individual effects overlap and sum together at each point in space. This results in a new wave pattern that is the sum of the original waves.

When two or more waves are at the same place at the same time the resulting effects is called?
When two or more waves are at the same place at the same time, the resulting effect is called interference. Interference can be either constructive, where the waves combine to create a stronger wave, or destructive, where the waves cancel each other out.
