Jwb no 13 sama cara ( butuh cpt)

R1 = 2 ohm
R2 = 3 ohm
R3 = 6 ohm
ketiga hambatan dipasang paralel
maka hambatan penggantinya =

Rp = 1/ (1/R1 + 1/R2 + 1/R3)
= 1/ (1/2 + 1/3 + 1/6)
= 1/ (1)
= 1 ohm

arus utama (I)
I = V / Rp
I = 3 / 1
I = 3 A

arus pada cabang I2 =
I2 = V / R2
I2 = 3 / 3
I2 = 1 Ampere

semoga cukup jelas dan membantu
