Sine Wave Characteristics
AC power is represented graphically by a sinusoidal or sine waveform. -- called sine wave for short. As you look at this sine wave, remember that this apparently stable picture changes 60 times every second. In doing so, we think in terms of averages of current, voltage and any changes in frequency. There are five characteristics of AC power; Amplitude, Cycles, Frequency, Peak to Peak, and RMS.
