Hello, I'm in my 2nd year of EE. I have done circuit analysis and some basic into to diodes, transistors and op-amps. We have a class in which we are given circuits for a audio amplifier and a power supply. We are required to understand the circuits completely. How they work and why each...

I like this: https://www.amazon.com/Fundamentals-Electric-Circuits-5th-ebook/dp/B008K9U418/ref=sr_1_2?s=digital-text&ie=UTF8&qid=1369628670&sr=1-2&keywords=sadiku+Circuit+Analysis I used the 4th edition.

I just finished my first year of EE. I have 3 months free and plan to go over this book. How much should i expect to cover in 3 months? Should I set a time limit (e.g 1 week) per chapter or take as much time needed to reasonably understand the material?

Sure, here is the syllabus: http://www.2shared.com/document/tJaIRBI6/HET183_Unit_Outline__Sem2_2011.html"

This is my first semester as a EE undergrad and I'm having difficulty with my telecom class. These are my current classes: Physics Calculus Intro to C Programming Electronics and telecommunications. Everything else is fine. For telecom, I don't know why they are making us do it in the...

Your 15 and have gone through these !? I am in the same level as the OP. I am starting with linear algebra.

Make a personality within yourself that says "Prove to me that you understand". And then you say to that personality, i'll prove by showing that I can do all the assignments! :P

Sorry for replying late, I have a final for this intro mechanics tomorrow morning :) This is the way i did it : E1 (energy at lower orbit) = -GmM/2r1 where r1 is the radius of Mars + 1000 km E2 (energy at higher orbit)= -GmM/2r2 , r2 is the radius or Mars + 1000 km m is 2700 kg M is mass of...

Are you using a negative for U ?

If I had a choice between MIT and some other university, I would choose MIT for sure. I agree that you can have better teachers in other universities. But like twofish-quant said, there is a lot of other things in top universities that other universities may not have.

The moment of inertia about the axis (center in this case) is just MR^2, you don't need to use the parallel axis theorem. And torque is zero if the force goes through the axis of rotation. The Tensions are on the side (tangent) of the cylinder, not center.

Using integration :) There is an example or two in almost every physics text that i have seen. Check out some other books if your book doesn't have it.

When you are integrating to calculate the moment of inertia (MOI), you take the MOI of a tiny mass and sum all of those to get the total. MOI of a point mass is mr^2. In this case the tiny mass is a disk. MOI of a solid cylinder, disk etc is 1/2 mr^2.

You have to consider which force is doing the work in addition to the direction. Gravity is the force that does work on you, and since it's direction is opposite to your motion, the work is does is negative.

You can imagine the man walking on the x-axis towards the y-axis. Call his position x and the length of his shadow s. The key to these types of problems is using similar triangles. So we can get a relation between s and x. (1.8/s) = (7/x+s) Get s on one side and differentiate with respect to...
