Have an exam tomorrow morning and not sure where else to ask at this hour!
Going through some notes and my tutor put:
i1=i2+ (3-8i/4) => i1=3/4 +3i2
I keep getting 2 different answers. Am I right that it should actually be:
i1=3/4-i2? My tutor is prone to mistakes however I doubt my own maths abilities (long story-too much moving around from country to country caused my maths to take a hit often on the easier stuff)!
Would really appreciate your help!
Thanks!
What's latex? (Unless you're actually talking about the rubber material which i can't imagine!)
By i1 and i2 do you mean i_1 and i_2? -Asnwer is YES
Does (3-8i/4) mean - A. \frac{3 - 8i}{4} YES
And what is i meant to mean? Does it matter what i means?
I'm solving equations for circuit analysis. i is the current in a loop. The equation comes from using loop analysis and KVL. Stuck on just this part.
Thanks a million!
Doh!
Apologies!
"Well since it doesn't appear in i1=3/4 +3i2 (the thing you're trying to get to) and it does appear in i1=i2+ (3-8i/4) (the thing you start with),
yes!! it does matter! Have you just forgotten to include it in i1=3/4 +3i2? Or have you given it a value?"
Yes my mistake!
Starting with i1=i2+ (3-8i2/4)
According to tutors notes this goes to:
i1=3/4 +3i2
I'm getting:
i1=3/4 -i2 instead!
This is what I am trying to solve.
And yes it's (3-8i2) ALL over 4.
(Dealing with 2 currents here i1 and i2)
Hope I'm being clear now.
Sorry about that!
Good point colby...didn't think about it....though it's not helpful going through tutorial soltuions the days before the exam and puzzling over silly mistakes he's made. I think he could have kept his mistakes to the blackboard!
Just hoping he's not as bad as that when it comes to correcting the papers! Thanks
