hambatan pengganti untuk rangkaian tersebut adalah..

R seri1 = 6 ohm + 2 ohm = 8 ohm
1/R paralel1 = 1/Rseri1 + 1/8
= 1/8 + 1/8 = 2/8
R paralel1 = 8/2 = 4 ohm
1/R paralel2 = 1/3 + 1/3 +1/3 = 3/3
R paralel2 = 1 ohm
R total = R paralel 1 + 9 ohm + R paralel2
= 4 ohm + 9 ohm + 1 ohm = 14 ohm
semoga membantu
