R1 = 10 ohm
R2 = 20 ohm
R3 = 25 ohm
R4 = 50 ohm
Dit:
a. Hambatan terbesar...?
b. Hambatan terkecil....?
jawab:
a. Hambatan terbesar di peroleh jika di rangkai seri
Rs = R1 + R2 + R3 + R4
Rs = 10 + 20 + 25 + 50
Rs = 105 ohm
b. Hambatan terkecil diperoleh jika di rangkai paralel
1/Rp = 1/R1 + 1/R2 + 1/R3 + 1/R4
1/Rp = 1/10 + 1/20 + 1/25 + 1/50
1/Rp = 10/100 + 5/100 + 4/100 + 2/100
1/Rp = 21/100
Rp = 4,7 ohm
