1/Rbc = 1/R2 + 1/R3 + 1/R4
1/Rbc = 1/8 + 1/4 + 1/8
1/Rbc = 1/8 + 2/8 + 1/8
1/Rbc = 4/8
Rbc = 8/4 = 2 ohm
kemudian Rbc diseri dgn R1
Rtotal = Rbc + R1
Rtotal = 2 + 4 = 6 ohm
Rac = Rtotal = 6 ohm
.
b. -E1 - E2 + IR = 0
-6 -6 = - IRtotal
-12 = - I 6
I = 2 A
c. V = I Rtotal
V = 2 . 6
V = 12 volt
d. Vbc = I.Rbc
Vbc = 2 x 2
Vbc = 4 volt
.
I2 = Vbc/R2 = 4/8 = 0,5 A
I3 = Vbc/R3 = 4/4 = 1 A
I4 = Vbc/R4 = 4/8 = 0,5 A
