Question

Помогите решить задачу по физике.

Answer 1

$R _{0}=R _{1 - 3}+R_{4}+R_{5}+R_{6} \\ \frac{1}{ R _{1 - 3}} = \frac{1}{R_{1}}+ \frac{1}{ R _{2}}+ \frac{1}{ R _{3}}= \frac{R_{1}+R_{2}+R_{3}}{R_{1}*R_{2}*R_{3}}= \frac{6}{6} = \ \textgreater \ R _{1 - 3}= 1 \\ R _{1 - 3}+R_{4}+R_{5}+R_{6}=1+1+2+3=7$
