| Mar 30, 2020 at 7:14 | comment | added | skvery | Have a look at the real and imaginary components of \$V_M\angle \phi\$. \$a = \text{Re}(V_M\angle \phi) = V_M\cos(\phi)\$ and \$b = \text{Im}(V_M\angle \phi) = V_M\sin(\phi)\$. Now \$V_M\angle \phi = a+jb\$. You now have the polar form with components \$V_M\$ and \$\phi\$, and the rectangular form with components \$a\$ and \$b\$. You use the rectangular form to add and subtract, and the polar form to divide and multiply. You can also use the rectangular form to multiply \$(a+jb)\cdot(c+jd) = (ac-bd)+j(ad+bc)\$. | |
