My head hurts from this.

358.82 to be exact.

Close enough.

Doesn't matter, unless your teacher is terrible at explaining things. Don't worry about making one huge equation, solve little parts of the circuit first.

I'm gonna assume you're taking physics 2. Circuits was the easiest part of both physics classes, except maybe optics.

It's an intro engineering course. http://img177.imageshack.us/img177/6380/notgood.jpg Most people in the class are not doing so hot. The grading is really annoying and the tests require more time than what you're given.

 

[rcpratt]

That's the point. Intro to engineering classes are weed-out classes.

Stop making fucking excuses, your grade does not depend on other students. Why do you care if others are not doing so good?

 

[TridenT]

Anyway, I got the answer after some weirdness. I don't know how I did it, I'll have to look at my paper again... but I got it. http://img59.imageshack.us/img59/2807/rageasorous.jpg

This is week 2 of Intro to EE. If you're having trouble now, it should be concerning to you.

Granted, I struggle a bit in my intro to EE class (but not this soon) and then went on to do fine in the harder classes.

It's not that hard if it's explained well. >_>

We don't do enough examples in class for the topics we cover I think. I learn a lot better from examples.

But the answer is 359 Ohm.

Once you get past the introductory courses, engineering is mostly self taught. The professor will introduce the concept, a formula, and maybe do one example.

Its not like high school where you learn a concept and then do 20 examples showing every possible type of question involving the concept.

Its very important that you can take the concepts you've learned and apply them to problems you've never seen before. A lot of exams are like this. I've had several professors say something along the lines of "you know its a good exam when you learn something while taking the exam".

Btw, don't worry if you can't teach yourself yet. You should be slowly learning to be more independent with your learning.

OH MY GOD, IS THAT BLACKBOARD?!?!?!?!?!?!?!

Fuck I hate blackboard

 

[RPD]

seriously? those are the easiest things ever

I really hope you aren't an EE. Even as a mechanical engineer that diagram was the equivalent of the square root of 4 in math.

 

[DangerAardvark]

Dude, this shit is so easy.

Yes, it's blackboard.

arent you going to uw now? or you're at a CC?

but ya could also try brute forcing KCL at each node and going from there (apply test voltage and such)

lulz

Try taking microprocessors. The professor has free reign to ask some really absurd shit. For example, this line might as well read "I am a complete time vampire, skip me!"

"Make a hardware modification that allows you to..."

HATE. THAT. SHIT. 90 minutes to complete a 9 page exam, the last thing I want to do is flip through the fucking manual of a commercial DSP to make some adjustments to the architecture. It usually involves creating some new addressing mode, but include the word "pipeline" in there and I wont even bother.

 

[Sea Moose]

you fail trident, i can even do that and i am a dumbarse

 

[Taejin]

lol intro to engineering course? haha..

 

[micaturbo]

wish i had 15% finals...

 

[evident]

man i just solved this problem and i haven't done this in like 8 years

 

[Cogman]

You know, this problem would have been simpler with a Laplace transform. (tee he he)

 

[Number1]

Wow there are a lot of people in here who are much more intelligent then the OP.









Or at least that's what they think, LOL

There is a name for this condition:
Dunning–Kruger effect

WTF? Why on EARTH would you apply KCL in this situation... thats just making things WAY more complicated then they need to be. This is a simple application of parallel/serial resistor laws. Really pretty basic stuff.

Op, if your still not getting it. Work right to left. Combine all resistors that aren't split into branches (IE, if you can walk from one resistor to the next without touching a branch, then they are serially connected.) and go from there. If you can't do that mentally, use the paper, write down the full circuit each time you combine resistors into an equivalent resistance. It really is just an application of the laws Rp = 1/(1/r1 + 1/r2) Rs = (r1 + r2)

Intro to EE was a fun class for me, Mon/Wed spent on mostly lecture/easy quizzes, Fri - someone from industry came in to talk, sometimes with free company junk you usually get at career fairs.
