I have this assignment, basically I had to do the same thing in simplified way and then superposition theorem. Apparently the answers don't match. I'm pretty sure the mistake is in superposition theorem. It could be some really stupid and simple mistake I made since I'm no good at this at all.(adsbygoogle = window.adsbygoogle || []).push({});

I'd be really grateful if anyone could help me fix it.

I=U/R

I1=-2,2 I1=5/10

I2=0,4 I2=15/10

I3=-1,8 I3=30/10

K1=I1-I2+I3

K2=E1-E2=I1*R1*R2

K3=E2-E3=I2(R2+R3)

K2=5-15=I1*10+I2*15

I1=10+20+15I2=30+15I2

K22=15*30=I2=(-15)+I3*15

I2=15+30-15+15I3=153

16I2=15I1

I2=0,938I1

I1=30+15*0,938I1

I1=30+I10,7I1

-13,07I1=30

I1=-2,2

I2=0,938*(-2,2)

I2=0,4

I3=-2,2-(-0,4)

I=-1,8

R1kogu=R1+(R2*R3)/R2+R3

R1kogu=10+(15*15)/15+15=10+7,5=17,5

I1=E1/R1total=5/17,5=0,286

U1=R1*I1=17,5*0,286=5,005

I2=U2/R2

I2=0,005/15=0,0003

I3=0,0286-0,0003

I3=0,2867

RtotalR2=(R1*R3)/(R1+R3)=15+(10*15)/(10+15)=6+15=21

I2=15/21=0,714

U2=R2*I2=15*0,714=10,71

U1=U2=E2-U2=15-10,71=4,29

I3=4,29/15=0,286

I1=I2+I3=0,714+0,286

R3total=R3+(R1*R2)/(R1+R2)=15+(10*15)/(10*15)=21

I'''3=15/21=0,714

U3=R3*I'''3=15*0,714=10,71

U1=U3*E3-U3=15-10,71=4,29

I''2=4,29/15=0,286

I'''1=I2+I3=0,714+0,286=1 A

Current: 1A, I2 = 0,286 and I3 = 0,714

So this is it, any kind of help would be greatly appreciated. Thanks for your time.
