U_2X = I_3X*R₂ = -0.869 * 1 = -0.869 B

U_3X = I_3X*R₃ = -0.869 * 1 = -0.869 B

U_4X = I_4X*R₄ = 0.326*6 = 1.956 B

U_6X = I_4X*R₆ = 0.326*4 = 1.304 B

U_1X + U_6X – U_2X = -E₂ + E₁

U_1X = -1.304 + 0.869 -10 + 5 = - 5.42 B

R10 = R6 + R7 = 4.75 Ом

R11 = R4 + R9 = 6.75 Ом

R_K = 2.788 + 0.125 = 2.913 Ом
