Homework Statement



I am trying to find the answer to this questions and I am reading ahead of my exams this next January . And I am going through the past questions

a. Determine current flowing through 2 ohms resistor using superposition and nortons theorem

Please I need a site that can give different examples on how to solve more complex questions Please I just like your help. It will prepare me a lot

Thank you.

Thevenems:
3*12=8I 36=8I
I=4.5A 36V=8*4.5A+Vab Vab=0V

Rt =8+12=20R

I = 0/2R+20R
I=0A

Nortons = In=I8 + I12
I8=36/8=4.5A I8=36/12=3A
In=4A+3A
In =7A



Find RT= 2*(8+12)/2+8+12=40/22
RT=20/11

I = 7*20/11/20/11+2=140/42/11

Hi, sorry to say that I didn't understand your question. First, what is 8R? Is it a 8ohms resistor? What is your 3A? Is it a 3 amperes current flow? Maybe if u can attach a more clearer circuit diagram, I might be able to help you.
We use superposition when we interfere several sources in the circuit. I had a hard time studying in this kind of chapter before during my first semester in university, but it will be so easy when you try a lot of questions and understand how to apply on it.
My experience told me that if you are willing to spend your time on exercises, don't worry, you will be able to score.
