Объяснение:

$U_2 = I_2R_2 = 8*4 = 32~V\\U_1 = U_2 = U_3 = U_4 = 32~V\\I_1 = \dfrac{U_1}{R_1} = \dfrac{32}{3} = 10.67~A\\\\I_3 = \dfrac{U_3}{R_3} = \dfrac{32}{16} = 2~A\\\\I_4 = \dfrac{U_4}{R_4} = \dfrac{32}{4} = 8~A\\\\R_{1234} = \dfrac{R_{12}R_{34}}{R_{12} + R_{34}} = \dfrac{\dfrac{R_1R_2}{R_1 + R_2}\dfrac{R_3R_4}{R_3 + R_4}}{\dfrac{R_1R_2}{R_1 + R_2} + \dfrac{R_3R_4}{R_3 + R_4}} = \dfrac{\dfrac{3*4}{3+4}\dfrac{16*4}{16+4}}{\dfrac{3*4}{3+4} + \dfrac{16*4}{16+4}} = 1.1163~Om$

$I_{1234} = I_5 = \dfrac{U_{1234}}{R_{1234}} = \dfrac{U_1}{R_{1234}} = \dfrac{32}{1.1163} = 28.67~A$

$U_5 = I_5R_5 = 28.67*15 = 430~V$

$R_0 = R_{1234} + R_5 = 16.1163~Om\\I_0 = I_5 = 28.67~A\\U_0 = U_{1234} + U_5 = 32+430 = 462~V$
