Polaritas Electrica: Quid est?
Nunc considera circuitum AC cum duabus fontibus voltage. Hic, magnitudo, polaritas, et angulus phase utuntur ad inveniendum voltage equivalentem.
In prima figura, ambo fontes habent eandem polaritatem. Itaque, voltage equivalentis est additio amborum. Sed haec sunt forma polaris—
![\[ V_1 = 20 \angle 0^\circ \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-2f2c08cd6629a2e7536d5e9c1dc09955_l3.png?ezimgfmt=rs:89x16/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
![\[ V_2 = 5 \angle 60^\circ \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-075ba19cbb0c3ac897034e0d4b1666dc_l3.png?ezimgfmt=rs:89x16/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
Primum opus est convertendi hanc formam polarem in formam rectangularis. Et erit—
![\[ V_1 = 20 + j0 \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-a6eb419b488a4f26e7c0b71b556da47f_l3.png?ezimgfmt=rs:98x16/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
![\[ V_2 = 2.5 + j4.33 \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-0b67db76e96036dea77d076d48247020_l3.png?ezimgfmt=rs:126x17/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
Nunc, voltage equivalentis est additio uniuscuiusque X-componentis et Y-componentis (i.e. 
)—
![\[ V = 22.5 + j4.33 \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-aa02674f4f19c5b8cdc3e2d00935162b_l3.png?ezimgfmt=rs:132x17/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
Iterum, convertamus formam rectangularis in formam polarem et obtinebimus—
![\[ V = 22.913 \angle 10.89^\circ \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-2185ebf2e079cf639e55af5013beb574_l3.png?ezimgfmt=rs:148x14/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
In secunda figura, ambo fontes habent oppositas polaritates. In hoc casu, voltage equivalentis est subtractio amborum voltagium—
![\[ V_2 = - ( 5 \angle 60^\circ ) = 5 \angle 300^\circ \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-4ec4716142bc830cf87b3af9823cd7fd_l3.png?ezimgfmt=rs:196x19/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
Nunc, possumus addere ambo 
et 
ad inveniendum voltage equivalentem—
![\[ V_1 = 20 \angle 0^\circ = 20 + j0 \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-4a95578cf612d7256b266121b962b529_l3.png?ezimgfmt=rs:169x18/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
![\[ V_2 = 5 \angle 300^\circ = 2.5 - j4.33 \]](https://www.electrical4u.com/wp-content/ql-cache/quicklatex.com-0f3a65324296b05d22a5daa19c9c0d65_l3.png?ezimgfmt=rs:206x18/rscb38/ng:webp/ngcb38 "Rendered by QuickLaTeX.com")
Primum, opus est convertendi hanc formam polarem in formam rectangularis. Et erit—
