Answer 1

Ответ:

Объяснение:

$\dfrac{1}{R_{12}} = \dfrac{1}{R_1} + \dfrac{1}{R_2} = \dfrac{1}{1} + \dfrac{1}{2} = \dfrac{3}{2} \to R_{12} = \dfrac{2}{3}~Om\\\dfrac{1}{R_{34}} = \dfrac{1}{R_3} + \dfrac{1}{R_4} = \dfrac{1}{2} + \dfrac{1}{1} = \dfrac{3}{2} \to R_{34} = \dfrac{2}{3}~Om\\R_{14} = R_{12} + R_{34} = \dfrac{4}{3}~Om\\R_{56} = R_5 + R_6 = 6~Om\\\dfrac{1}{R} = \dfrac{1}{R_{14}} + \dfrac{1}{R_{56}} = \dfrac{3}{4} + \dfrac{1}{6} = \dfrac{11}{12} \to R = \dfrac{12}{11}~Om$
