With an oscilloscope. Measure the vertical height of the wave on the screen . Multiply that by the volts per division setting. That will give you its' voltage.
Neither. A.C. voltage, and current, are expressed as root-mean-square (rms) values, and this is what a voltmeter and an ammeter reading will indicate. To measure peak voltage, or peak-to-peak voltage, you will need to use an oscilloscope.
To measure peak voltage using an oscilloscope, adjust the voltage scale setting on the vertical axis until the entire waveform is visible on the screen. Then, use the cursors or measurement tools on the oscilloscope to determine the maximum amplitude of the waveform, which represents the peak voltage. You can directly read the peak-to-peak value if it's available, or calculate it by multiplying the peak voltage by 2 if only the peak amplitude is displayed.
you take the peak voltage and divide it by the square root of 2 100/1.414= 70.7 volts rms This is true only for sine wave. For other waveforms like a triangle signal it is different.
4V peak to peak
Peak purity index is a measure used to assess the homogeneity of a peak in chromatographic analysis. It compares the absorbance or response of a peak at different points within the peak to determine its purity. A peak with a high peak purity index indicates that the analyte in the sample is pure and unaffected by co-eluting substances.
If two waveforms are out of phase by 90 degrees, this is a quarter cycle. If you are looking at a symmetric sine wave that oscillates around zero then one wave will be at its peak value when the other will be at zero crossing point.
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.
To convert DC values to AC values if you are wanting RMS values they are the same. 100V DC and 100V AC (RMS) are the same "value". If you want to know the Peak-To-Peak AC value you would multiply the RMS value by 1.414. So 100V AC RMS equals 141.4 V Peak to Peak.
It is the distance from peak to peak (or trough to trough) of a wave.
peak - peak.
To determine the wavelength of a wave, you need to measure the distance between two consecutive points that are in phase with each other, such as peak to peak or trough to trough. This distance represents one complete cycle of the wave and is equal to the wavelength. The symbol for wavelength is λ and is usually measured in meters.
The relationship between wavelength and peak voltage depends on the type of wave. In electromagnetic waves like light or radio waves, there is no direct correlation between wavelength and peak voltage. However, in signals like electrical voltage waveforms, the peak voltage is often correlated with the frequency of the wave.
