R1 2ohm R2 4ohm R3 1ohm R4 3ohm R5 1ohm

R1 = 2

R2 = 4

R3 = 1

R4 = 3

R5 = 1

Jika dirangkai seri

maka

RS = R1 + R2 + R3 + R4 + R5

RS = 2 + 4 + 1 + 3 + 1

RS = 11 Ω

jika dirangkai paralel

1/Rp = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5

1/Rp = 1/2 + 1/4 + 1 + 1/3 + 1

1/Rp = 6/12 + 3/12 + 12/12 + 4/12 + 12/12

1/Rp = 37/12

Rp = 12/37 Ω

Maksudnya ini apa yah
