When a sinusoidal voltage is applied to a non-linear circuit, both the resulting current and the voltage waveform become non-sinusoidal. Through Fourier series decomposition of these non-sinusoidal waves, the component with a frequency equal to the power system frequency is identified as the fundamental wave, while components with frequencies higher than the fundamental are termed harmonics. A vas...
