Объяснение:
U1 = R1*I1 = 4 * 3.314 = 13.256 B
r45 = R4+R5 = 5 + 2 = 7 Ом
r456 = r45*R6 / (r45+R6) = 7*2 / (7+2) = 1.556 Ом
U6 = I1 * r456 = 3.314 * 1.556 = 5.157 B
I4 = U6 / (r45) = 5.157 / 7 = 0.737 A
U3 = U2 = U - U1 - U6 = 35 - 13.256 - 5.157 = 16.587 В
I2 = U2 / R2 = 16.587 / 6 = 2.765 A
I3 = I1 - I2 = 3.314 - 2.765 = 0.549A
R3 = U3 / I3 = 16.587 / 0.549 == 30.213 Ом
