The Total Harmonic Distortion (THD) is the ratio of

(a) rms value of all the harmonic components to the rms value of the fundamental component

(b) average value of all the harmonic components to the rms value of the fundamental component

(c) rms value of all the third harmonic component to the rms value of the fundamental component

(d) rms value of all the fundamental component to the rms value of all the harmonic components

The question was posed to me by my school teacher while I was bunking the class.

My doubt stems from Single Phase VSI-5 in section Inverters of Power Electronics

Correct option is (a) rms value of all the harmonic components to the rms value of the fundamental component

For explanation: THD = Vo/V1

V1 = Fundamental component

Vo = value of all the harmonic components expect the fundamental.
