решение
R2 || R3
1/R23 =1/R2 +1/R3 = 1/2 +1/3 = 5/6 ; R23 = 6/5 = 1.2 Ом
R123 = R1+R23 = 1.8+1.2 = 3 Ом
R123 || R4
1/R = 1/R123 + 1/R4 = 1/3 + 1/6 =3/6 = 1/2 ; R = 2 Ом
I = E / (R+r) = 7.5 / (2+0.5) = 7.5/2.5 = 3 A
U = R*I = 2*3 = 6 B
U123 = U4 = U = 6 B
I4 = U4/R4 =6/6 = 1 A
I1 = I123 = U123/R123 = 6/3 =2 A
U1 = I1*R1 = 2*1.8 =3.6 B
U2=U3 = U123 -U1 =6 - 3.6 = 2.4 B
I2 =U2/R2 = 2.4/2 =1.2 A
I3 =U3/R3 = 2.4/3 =0.8 A
