poin gedee, a.Tentukan hambatan pengganti b.arus pada masing hambatan c.tegangan pada masing hambatan d.daya pada masing hambatan

a) 1/Rp1 = 1/R1 + 1/R2 = 1/10 + 1/20 = 3/20
Rp1 = 20/3 ohm
1/Rp2 = 1/R3 + 1/R4 = 1/30 + 1/40 = 7/120
Rp2 = 120/7 ohm
R total = Rp1 + Rp2 = 20/3 + 120/7 = 500/21 ohm

b) E total = 24+12+5 = 41 volt
I = E total/R total = 41 : 500/21 = 1,722 A
I1 : I2 = 20 : 10 = 2 : 1
I1 = 2/3 × 1,722 = 1,148 A
I2 = 1/3 × 1,722 = 0,574 A
I3 : I4 = 40 : 30 = 4 : 3
I3 = 4/7 × 1,722 = 0,984 A
I4 = 3/7 × 1,722 = 0,738 A

c) V1 = I1. R1 = 1,148×10 = 11,48 V
V2 = V1 = 11,48 V
V3 = I3. R3 = 0,984×30 = 29,52 V
V4 = 29,52 V

d) P1 = V1. R1 = 11,48×10 = 114,8 W
P2 = V2. R2 = 11,48×20 = 229,6 W
P3 = V3. R3 = 29,52×30 = 885,6 W
P4 = V4. I4 = 29, 52×40 = 1.180,8 W
