Help with Electronics Questions

[jack.mitchell]

So, I've got resits coming up in September for university and i'm trying to hack my way through a Circuits & Systems paper. My uni have been gracious enough to provide me example question papers but no solutions. Therefore I thought I would ask here if someone who is more qualified in this area could help me make my way through it. I've already done this question and got answers but it would help if I could get clarification to see if i've done them correctly, i'm not asking anybody to do my exam questions for me (what would be the point?). Anyway below is a screenshot of the question and my answers:



1.

i) 0.625 ohms

ii)

A-B = 8A
R1 = 1.875A
R2 = 3.675A

I think I have i) and ii) A-B right but i'm not sure on the others, any help would be appreciated!

Ahh OK, I get it guys, much clearer now. I'm slowly getting my head round it, whats annoying is that I can put the theory into use in practise but shove an exam in front of my face expecting you to do things a certain way then I find it difficult. I may come back with more yet but I'll see how i get on. Thanks again.
