R1 nt [ (R2 nt R3 ) // R5 ] nt R4
\(I_1=I_{235}=I_4=\dfrac{U_{AB}}{R_{td}}=\dfrac{24}{\dfrac{\left(4+6\right).10}{4+6+10}}=2\left(A\right)\\ \Rightarrow U_1=I_1R_1=2.4=8V\\ U_4=I_4.R_4=2.3=6V\\ \Leftrightarrow U_1+U_{235}+U_4=24\\ \Leftrightarrow8+U_{235}+6=24\\ \Rightarrow U_{235}=10V\)
\(\Rightarrow U_{23}=U_5=10V\\ \Rightarrow I_5=\dfrac{U_5}{R_5}=\dfrac{10}{10}=1\left(A\right)\\ \Leftrightarrow I_{23}+I_5=I_{235}\Leftrightarrow I_{23}=2-1=1\left(A\right)\\ \Leftrightarrow I_2=I_3=1A\)
