70% to passAs shown in the illustrated harmonic analysis diagram, which figure represents the fundamental (or first harmonic)? Illustration EL-0163
AA
BB
CC
DD
AI Explanation
The correct answer is B. The fundamental or first harmonic in the harmonic analysis diagram shown in Illustration EL-0163 is represented by figure B. This is because the fundamental harmonic corresponds to the lowest frequency or longest wavelength component of the periodic waveform. In the diagram, figure B depicts the fundamental or first harmonic, while the other figures (A, C, and D) represent higher-order harmonics with shorter wavelengths. The other options are incorrect because they do not depict the fundamental or first harmonic of the waveform.
