Дано :
R1 = 3 Ом

R ( общие ) = ( R2 * R3 ) / ( R2 + R3 ) + R1
R = ( 2 * 4 ) / ( 2 + 4 ) + 3 = (13/3) Ом
R23 = R - R1
R23 = (13/3) - 3 = ( 13 - 9 ) / 3 = (4/3) Ом
I = U/R
U = IR
U23 = I * R23
U23 = 6 * (4/3) = 8 B
U23 = U2 = U3 = 8 B
I1 = I = 6 A
I2 = U2 / R2
I2 = 8 / 2 = 4 А
I3 = U3 / R3
I3 = 8 / 4 = 2 А
ответ : I1 = 6 A
I2 = 4 A
