Hi,
RMS is voltage X .707 and the power is voltage X current.
Hope that helps,

The rms value of sinusoidal 200v peak to peak wave is?
You can work this out yourself. For a sinusoidal waveform the rms value is 0.707 times the peak value. As you quote a peak-to-peak value, this must be halved, first. Incidentally, the symbol for volt is 'V', not 'v'.
What is a Trumpets amplitude?
How loud the air vibration is from the bell of the instrument. Technically the maximum zero to peak value (0-90 degrees) of the sinusoidal waveform.
What is maximum current?
If you are referring to an a.c. current, then the maximum current is the amplitude of its waveform. For a sinusoidal waveform, the amplitude of an a.c. current is its root-mean-square value, divided by 0.707. For example, an a.c current with an rms value of, say, 10 A will have an amplitude of 14.14 A,
What is the RMS value of AC sinusoidal waveform?
General formula: square root of the square modulus averaged over a period:xRMS =1/T sqrt( integral (|x(t)|2dt) ) ,where x(t) is the signal and T is its period.If you solve it for sinusoidal waves, you get a 1/sqrt(2)~0.707 factor between peak amplitude and RMS value:xRMS ~ 0.707 XPK ~ 0.354 XPK-PK ~ ...
How do you find the peak value of 110 volts RMS?
The peak of a waveform that is purely sinusoidal (no DC offset) will be RMS * sqrt(2). This is the peak to neutral value. If you are looking for peak to peak, multiply by 2.
What is the Average value of AC over a half cycle?
The average value of an a.c. voltage or current, over a complete cycle, is zero. For this reason, the average value is normally quoted over a half cycle and, for a sinusoidal waveform, is equal to 0.637 Vmax or 0.637 Imax.
What is the value and peak to peak value of 12v?
All a.c. voltages are expressed in root-mean-square (r.m.s.) values, unless otherwise stipulated. So 12 V is an r.m.s value which, for a sinusoidal waveform, has an amplitude, or peak value, of 1.414 x 12 = 16.97 V. So its peak-to-peak value will be twice this amount -i.e. 33.94 V.
Why is the peak amplitude of voltage load lower than the amplitude of voltage transformer?
Unless otherwise stated, the value of an a.c. current or voltage is expressed in r.m.s. (root mean square) values which, for a sinusoidal waveform, is 0.707 times their peak value. The output of a voltage (or potential) transformer is no different, its measured voltage will be its r.m.s value which is lower than its peak value.
How do you calculate the peak-to-peak value of a sine wave?
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/0.707Once you know the value of the amplitude (Vmax or Imax), simply double it to determine the peak-to-peak value.
What is the difference between rms value and average value of AC?
rms value of ac power = dc power in reference to heat production in pure resistive load So ac power of some rms value will produce the same heat in resistive load as dc power will of same value
Why it is useful to use rms notation for alternating current and voltage?
AC waveform is sinusoidal waveform it has both positives and negative cycles so we dont have a standard constant value to do Measurements so instead of using AC quantities we use ROOT mean square values which is obtained by dividing Vpp(peak to peak voltage) by 1.414AnswerThe rms-value of an AC current is the same as as the value of DC current that will do the same amount of work. For example, 10 A (rms) AC will do exactly the same amount of work as 10 A DC.
Why different frequencies has same average value and RMS value?
Voltage and frequency are independent quantities.AnswerBecause the r.m.s. value is dependent on the shape of the waveform, not its frequency. The average value of any symmetrical waveform is zero and is independent of frequency.
