Webb12 maj 2010 · When two waves differ in phase by -90° or +90°, they are said to be in phase quadrature. When two waves differ in phase by 180° (-180° is technically the same as +180°), they are said to be in phase opposition. In time and frequency metrology, the phase difference is usually stated in units of time, rather than in units of phase angle. two mitigating circumstancesPeak values can be calculated from RMS values from the above formula, which implies VP = VRMS × √ 2, assuming the source is a pure sine wave. Thus the peak value of the mains voltage in the USA is about 120 × √ 2, or about 170 volts. The peak-to-peak voltage, being double this, is about 340 volts.
