Tlng ksh cara ny sklian yha

1.
Jadikan menjadi rangkaian seri,
1/Rp1 = 1/10 + 1/2
1/Rp1 = 6/10
Rp1 = 10/6 = 5/3 ohm

1/Rp2 = 1/7 + 1/21
1/Rp2 = 4/21
1/Rp2 = 21/4 ohm

Rs = R1 + R4 + Rp1 + Rp2
Rs = 5 + 5 + 5/3 + 21/4
Rs = 203/12
Rs = 16,92 ohm

2.
Rs = R1 + R2
Rs = 2 + 8
Rs = 10 ohm

R total = Rs + r
R total = 10 + 2
R total = 12 ohm

I total = v/R total
I total = 20/12
I total = 5/3 A
