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.

What is the form factor of sine wave?
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
What is a pure sine wave inverter?
The sine wave is a mathematical function that describes a smooth repetitive oscillation. An Inverter is an electronic device that converts power from one voltage to another.A pure sine wave inverter is a device that produces a smooth and consistent flow of electricity in the required voltage.The benefits of a pure sine wave inverter are that the device requiring the electricity from the inverter will not suffer from surges and lows in power output and as such the connected device will perform a lot better.
What is the effective value of an AC sine wave current having a peak-to-peak value of 8 amperes?
The rms value of a sine wave current is 0.707 Imax. So the answer to your quesion is 0.707 x 4 = 2.83 A.
What is RMS Peak value and average value?
RMS is used to determine the average power in an alternating current. Since the voltage in an A/C system oscillates between + and -, the actual average is zero. The RMS or "nominal" voltage is defined as the square root of the average value of the square of the current, and is about 70.7% of the peak value.************************************************************The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.Fo a sine wave, the r.m.s. value is 0.707 x the peak value.The average value is different; for a sine wave it is 0.636 x the peak value.
Why do you have to find RMS value?
Root mean square (average ***) voltageBecause ac (alternating current) does not warm up a lamp, heater, etc. as well as a direct current of the same value as the peak ac, we need to work out how to find the equivalent dc (direct current) voltage for the ac situation.The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.For a sine wave, the r.m.s. value is 0.707 times the peak value, or, conversely, the peak value is 1.414 times the r.m.s. value.Peak voltagePeak voltage is measured from the zero axis to the top of the curve. So, in the case of the UK mains supply, where the average r.m.s. voltage is 230 volts, Vpeak = √2 x Vrms = √2 x 230 V = 325.22 volts.Note: The average voltage is always zero.*** The average value and the r.m.s. value of a sine wave are not the same thing. The average value of a sine wave is 0.636 x the peak value.
What is the difference between pure sine wave and modified sine waves?
A pure sine wave has energy at only one frequency.Any other wave shape has energy at other frequencies in addition to the frequency of the obvious waveshape.If you add up enough sine waves with the right frtequencoies and amplitudes, they'll add up to form any shapeyou want, even a squarewave.
What is sine waves?
See the link belowA sine wave is computed by a mathematical function. A pure sine wave in a physical sense would exactly match the calculated value in the function at every point in time.
Ac current reffered as effective value?
Effective = RMS= average Not for a sine wave it isn't. The r.m.s. value of a sine wave is 1.11 x the average, or mean, value. The "effective" value is not a term which I've seen in any of my reference books.
What is the form factor of sine wave?
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
Is there a device that converts modified sine wave AC output from a generator to pure sine wave AC?
Well, a pure sine wave can only be produced as a pure sine wave. If it was modified to begin with, it would never be a pure sine wave. However, an actual generator should be supplying pure sine wave output, while something such as an inverter would be producing a modified sine wave.
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
Where can one purchase a Pure Sine wave inverter?
There are many places a person can buy a pure sine wave inverter. Some of these places are Amazon, Home Depot, Canadian Tire, Inverter Supply and eBay.
Does digital voltmeter measures rms voltage or peak to peak voltage or average?
Yes, most DMM are ''average responding", giving accurate rms reading if the ac voltage signal is a pure sine wave. They measure the average of the absolute value of ac voltage and are calibrated so that reading are corrected to that of the rms value of a sine wave.Error occur if harmonic are present.
How does a half wave rectified sine wave sound like?
It's hard to define a sound, but here's a try: A half-wave rectified sine sounds harsh and whiney. Not as sharp and jagged as a square wave, but not nearly as pure and smooth as a sine. The key is to realize that the half-wave rectified sine is a sine plus a significant load of harmonics, and wherever there is a lot of harmonic energy, we call it "total harmonic distortion". So the bottom line is, anything that isn't a pure sine, you would say it sounds "distorted".

Why a sine wave is a simple vertical line in a frequency domain?
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.
