tolong yah kak tugas hari ini

R1, R2, R3 pararel
[tex] \frac{1}{rp} = \frac{1}{r1} + \frac{1}{r2} + \frac{1}{r3} \\ \frac{1}{rp} = \frac{1}{8} + \frac{1}{8} + \frac{1}{12} \\ \frac{1}{rp} = \frac{2}{8} + \frac{1}{12} = \frac{3 + 1}{12} \\ \frac{1}{rp} = \frac{4}{12} \\ rp = \frac{12}{4} = 3 \: ohm[/tex]
R4, R5 seri
[tex]rs \: = r4 + r5 = 3 + 10 = 13 \: ohm[/tex]
Rtotal = R seri + R pararel = 13 + 3 = 16 ohm
