What is the fundamental frequency in harmonics?

The harmonics are multiples of the fundamental frequency. So if the fundamental frequency is 100 Hz, the higher harmonics will be 200 Hz, 300 Hz, 400 Hz, 500 Hz, and so on. If the fundamental frequency were 220 Hz, the harmonics would be 440 Hz, 660 Hz, 880 Hz, and so on.

What causes 5th and 7th harmonics?

Magnetic cores, such as transformer and rotating machines that require third harmonic current to excite the iron. Synchronous machines (winding pitch produces fifth and seventh harmonics)

What determines fundamental frequency?

In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum of harmonically related frequencies, or the frequency of the difference between adjacent frequencies.

Why are odd harmonics harmful?

The rapid increase in electric current exactly happens at the 3 r d harmonic making it dangerous for circuits. These harmonics cause malfunctioning of devices and heating.
