that's the exercise
and my solution
calculations for A,B,C (1.1)
\(-I_1 +I_3 + I_5 = 0\)
\(-I_3 + I_4 - I_6 = 0\)
\(I_2 -I_4 -I_6 = 0\)
calculations for I, II, III (2.1)
\(-U_1 -U_3 +0 = 0\)
\(-U_2 -U_4 -0 = 0\)
\(U_3 + U_4 + 25 = 0\)
because \(U_6=0, E_5=25V\)
i use resistors \(R_1,R_2,R_3,R_4\) in this formula \(U_i=R_iI_i\)
and i have got (2.2)
\(-2I_1 -8I_3 = 0\)
\(-1I_2 -9I_4 = 0\)
\(8I_3 + 9I_4 + 25 = 0\)
i try to calculate from 1.1 and 1.2 this current \(I_6\) (i thinks this is what i need to find), but i cannot obtain the result. by the way calculations are too complicated for an exercise like this
greetings!
