Yang C dan D Hitunglah Hambatan Totalnya......

c]
R1 = 100 ohm
R2 = 150 ohm
R3 = 150 ohm
R4 = 100 ohm

1/Rp (i) = 1/R1 + 1/R2
1/Rp (i) = 1/100 + 1/150
1/Rp (i) = 3/300 + 2/300
1/Rp (i) = 5/300
Rp (i) = 300/5
Rp (i) = 60 ohm

1/Rp (ii) = 1/R3 + 1/R4
1/Rp (ii) = 1/150 + 1/100
1/Rp (ii) = 2/300 + 3/300
1/Rp (ii) = 5/300
Rp (ii) = 300/5
Rp (ii) = 60 ohm

Rt = Rp (i) + Rp (ii)
Rt = 60 + 60
Rt = 120 ohm

d]
R1 = 120 ohm
R2 = 140 ohm
R3 = 50 ohm
R4 = 50 ohm
R5 = 150 ohm

1/Rp = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5
1/Rp = 1/120 + 1/140 + 1/50 + 1/50 + 1/150
1/Rp = 35/4200 + 30/4200 + 84/4200 + 84/4200 + 28/4200
1/Rp = 261/4200
Rp = 4200/261
Rp = 16,09 ohm
