Bantu jawab lagii yaaa makasihh :))

1][
1/Rp = 1/R2 + 1/R3
1/Rp = 1/20 + 1/20
1/Rp = 2/20
Rp = 20/2
Rp = 10 ohm

Rs = R1 + R4
Rs = 20 ohm + 20 ohm
Rs = 40 ohm

Rtot = Rp + Rs
Rtot = 10 + 40
Rtot = 50 ohm

2][
a) 1/Rp = 1/R2 + 1/R3
1/Rp = 1/3 + 1/6
1/Rp = 2/6 + 1/6
1/Rp = 3/6
Rp = 6/3
Rp = 2 ohm

Rs = 1 ohm

Rtot = Rp + Rs = 2 + 1 = 3 ohm

b)
V = 6 V
I = V/R
I = 6/3 = 2 A

c)
I2 = Itot x R3/(R2 + R3)
I2 = 2 x 6/(3+6)
I2 = 2 x (6/9)
I2 = 2 x 2/3
I2 = 4/3 A

I3 = Itot x R2/(R2 + R3)
I3 = 2 x 3/(3+6)
I3 = 2 x (3/9)
I3 = 2 x 1/3
I3 = 2/3
