All AC voltages and currents are quoted as root-mean-square (rms) values where, for a sinusoidal waveform, the rms value is 0.707 Vmax or 0.707 Imax.
From this, you can determine the value of the amplitude Vmax or Imax:
Vmax = Vrms/0.707 or Imax = Irms/0.707
Once you know the value of the amplitude (Vmax or Imax), simply double it to determine the peak-to-peak value.

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 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 the peak value of a sine wave that has a peak to peak value of 60v?
30 volts provided zero crossing is at midpoint.
For same peak value of current which waveform will have least RMS value?
A square wave will have the highest value since it has a peak, positive or negative, all of the time. Other wave shapes such as triangular and sine, have a lower value than this.
A sine wave with an RMS value of 100 v would have a peak value of?
For a sine wave ONLY - and assuming you are talking plus and minus 100V (200V peak to peak) - the RMS voltage is about 71V. (One half square root of 2 * single sided peak value)
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.
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 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.
How do you calculate the form factor of a rectified sine wave?
i dont know,,,give me ans
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 derivation of the wave function?
A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
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.
What is the rms value for a sine wave oscillating between a -12mA and 12mA?
8.49mA
The peak value of a sine wave occurs?
For a standard 360 deg sine wave with starting point of 0 deg, peaks will occur at 90 deg and 270 deg.
How do you generate cos wave from sine wave?
By shifting the sine wave by 45 degrees.
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.

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.
