soal fisika berapa hasilnya

2) Rangkaian Paralel (Rp)
1/Rp = 1/R1 + 1/R2 + 1/R3 + 1/R4
1/Rp = 1/3 + 1/4 + 1/6 + 1/8
1/Rp = 8+6+4+3/24
1/Rp = 21/24
   Rp = 24/21 Ω

3) Rs + Rp + Rs                                                          (Rs=Rangkaian seri)
    1/Rp = 1/R2 + 1/R3 + 1/R4
    1/Rp = 1/2 + 1/6 + 1/4
    1/Rp = 6+2+3/12
    1/Rp = 11/12
       Rp = 12/11

Rs + Rp + Rs
6 + 12/11 + 7
66/11 + 12/11 + 77/11 = 155/11 Ω

4) Rp(ada Rs) + Rp(ada Rs)
    Rs1 = R1 + R2 = 8 Ω 
    Rs2 = R3 + R4 = 10 Ω

1/Rptotal = 1/Rs1 + 1/Rs2
1/Rpt       = 1/8 + 1/10
1/Rpt = 10+8/80
Rpt = 80/18 Ω
