Hamabatan pengganti beberapa hambatan berikut dengan beda potensial:4

a.

1/Rp =1/2+1/4+1/6 = 11/12

Rp = 12/11 = 1,1 ohm

Hambatan pengganti 1,1 ohm

b. Rs = 3+2+4 = 9 ohm

Hambatan pengganti 9 ohm

c. Rs = 2+4 = 6 ohm

1/Rp = 1/Rs + 1/6

1/Rp = 1/6 + 1/6 = 2/6

Rp = 6/2 = 3 ohm

Hambatan pengganti 3 ohm

d. 1/Rp = 1/3+1/6 = 3/6

Rp = 6/3 = 2 ohm

Rs = Rp + 4

Rs = 2 + 4 = 6 ohm

Hambatan pengganti 6 ohm
