R1 = 3 Ω

R2 = 2 Ω

R3 = 4 Ω

R4 = 6 Ω

R5 = 4 Ω

ditanya: nilai hambatan atau pengganti (R)?

Dijawab:

Rumus hambatan pengganti pada rangkaian seri

Rs = R1 + R2 + R3...Rn

Rumus hambatan pengganti pada rangkaian paralel

1/RP = 1/R1 + 1/R2 + 1/R3...1/Rn

Rs = R2 + R3 = 2 + 4 = 6 Ω

1/Rp = 1/R4 + 1/Rs

1/Rp = 1/6 + 1/6

1/Rp = 2/6

Rp/1 = 6/2

Rp = 3 Ω

Rs = R1 + Rp + R5

Rs = 3 + 3 + 4

Rs = 10 Ω
