Jika I total = 18Ð45⁰ A. Tentukan tegangan Vab !
Ib =Z24 / (Z24 +Z13) x IT
= 8j / (8j + 30) x 18 Ð45⁰
= 8 < 90 / 31,04 < 14.93 x 18 Ð45⁰
= 4,66 Ð 120,07⁰
Ia =Z13 / (Z13+Z24) x IT
= 30/(30+8j) x 18 Ð 45⁰
= 30<0 / 31.04 <14.93 x 18Ð45⁰
= 17,5 Ð30.07⁰
Vab ( searah jarum jam)
Vab = V20Ω + V6jΩ
= Ib (20) + -Ia
(6j)
=(4,66 Ð120⁰) (20) + (-17,5
Ð30⁰) (6j)
= (4,66 Ð120⁰) (20) + (-17,5
Ð30⁰) (6 Ð90⁰)
= 93,2 Ð120 - 105Ð120⁰
=-46,6 + 80,7 j – (-52,5 + 90,93 j)
=5,9 – 10,23 j
= 11,7 Ð -60 V

Tentukan impedansi Zab !
ZAB = (Z1
// Z2 ) + (Z3 // Z4)
Ø Zab = (Z1//Z2) + (Z3+Z4)
=
406,72 - 41,81 j +186,57 + 83,57 j
=
593,29 + 41,76 j
=
594,76 Ð 4,03⁰ Ω
