Olá!

Rs1 = R1+R2+R3\\
Rs1 = 1+2+3,5\\
Rs1 = 6,5 \ ohms

 \frac{1}{Rs2} =  \frac{1}{R1} +  \frac{1}{R2}\\\\
 \frac{1}{Rs2} =  \frac{1}{1} +  \frac{1}{1}\\\\
 \frac{1}{Rs2} =   \frac{2}{1}\\\\
Rs2 =  \frac{1}{2} \ ohms

Rs3 = Rs1 + Rs2 + 2,5\\
Rs3 = 6,5+0,5+2,5\\
Rs3 = 9,5 \ ohms

 \frac{1}{Rs4} =  \frac{1}{10} +  \frac{1}{10}\\\\
\frac{1}{Rs4} =  \frac{2}{10}\\\\
Rs4 = 5 \ ohms

Rs5 = Rs3 + Rs4\\
Rs5 = 9,5 + 5\\
Rs5 = 13,5 \ ohms

Rs6 = 2 +4\\
Rs6 = 6 \ ohms
\\\\
Rs7 = 1 + 1\\
Rs7 = 2 \ ohms


 \frac{1}{Rs8} =  \frac{1}{Rs6} +  \frac{1}{Rs7}\\\\
 \frac{1}{Rs8} =  \frac{1}{6} +  \frac{1}{2} \\\\
 \frac{1}{Rs8} =  \frac{4}{6}\\\\
Rs8 =  1,5 \ ohms

Rt = Rs5 + Rs8\\
Rt = 13,5 + 1,5\\
Rt = 15 \ ohms

A resistência equivalente do circuito é de 15 ohms.

Espero que tenha ajudado!
