Using the computed values of D_{2}=0.10, D_{3}=0.04, and  D_{4}=0.02 in Eq. (12.31),

\% THD =\sqrt{D_{2}^{2}+D_{3}^{2}+D_{4}^{2}+\cdots} \times 100 \%

we obtain

\% THD =\sqrt{D_{2}^{2}+D_{3}^{2}+D_{4}^{2}} \times 100 \%

 

=\sqrt{(0.10)^{2}+(0.04)^{2}+(0.02)^{2}} \times 100 \%=0.1095 \times 100 \%

= 10.95%
