Question

решите 5 пожалуйста!!!!!!!?

Answer 1

$frac{1}{R_{123}}=frac{1}{R_1}+frac{1}{R_2}+frac{1}{R_2}=frac{1}{15}+frac{1}{15}+frac{1}{15}=frac{3}{15}=frac{1}{5}\R_{123}=5(Om)\frac{1}{R_{45}}=frac{1}{R_4}+frac{1}{R_5}=frac{1}{6}+frac{1}{6}=frac{2}{6}=frac{1}{3}\R_{45}=3(Om)\R=R_{123}+R{45}+R_6=5+3+2=10(Om)$

Answer 2

Ro=R123+R45+R6=R1/3+R4/2+R6=15/3+6/2+2=10 Ом
