Odpowiedź:

R12=R1+R2

R123=R12*R3/(R12+R3)=R3*(R1+R2)/(R1+R2+R3)

Rz=R4+R123=R4+R3*(R1+R2)/(R1+R2+R3)

I=U/Rz

I=30V/R4+R3*(R1+R2)/(R1+R2+R3)

U4=I*R4

U4=R4*30V/R4+R3*(R1+R2)/(R1+R2+R3)

U3=U-U4

U3=30V-R4*30V/R4+R3*(R1+R2)/(R1+R2+R3)

U3=30{1-R4/[R4+R3*(R1+R2)/(R1+R2+R3)]}

I2=U3/R3

I2={30{1-R4/[R4+R3*(R1+R2)/(R1+R2+R3)]}}/R3

I1=U3/R12

I1=30{1-R4/[R4+R3*(R1+R2)/(R1+R2+R3)]}/(R1+R2)

U1=I1*R1

U1=R1*30{1-R4/[R4+R3*(R1+R2)/(R1+R2+R3)]}/(R1+R2)

U2=I1*R2

U2=R2*30{1-R4/[R4+R3*(R1+R2)/(R1+R2+R3)]}/(R1+R2)

ZAD2

I1=U/R1

I1=6,45V/1Ω

I1=6,45A

I2=U/R2

I2=6,45V/3Ω

I2=2,15A
