WebHarmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on. WebThe harmonic mean is the reciprocal of the average of the reciprocals of numbers. So the harmonic mean of a, b, and c is 3/ (1/a+1/b+1/c). It is used sparingly, but is well studied (e.g., the AM-GM-HM inequality). Just like how the arithmetic mean can be heavily swayed by large elements, the harmonic mean can be heavily swayed by small elements.
