Wow. I am impressed. Thank you so much for your help. Now I have a better idea on how reference nodes change voltages. THANKS!

I spoke with my professor through email. I asked her the same question on here. Which to my surprise she responded with "Take the reference point to the 20V power supply V2 will be 20V." I never responded to that email because it just confused me more and she never answer my original question as...

Hello all, I am working on a homework problem from class and I seem to be in another bind. I have found both voltages and the Current i1. However, both my voltages differ from what she has as answers, but my current for i1 is the same. She only gives us the final numerical value with no work in...

I did that shortly after posting this. And I got 85 volts. Can anyone confirm if that is correct?

Hello all. I am doing a basic circuit problem but ran got into a bind. I have a independent current source and need help finding the voltage drop of that current source. I did some research and found that current sources will always carry the same voltage as the power source no matter what's in...

I understand the problem, only if my approach was correct. The difference weight off both objects can be ignored when trying to find velocity of B after impact. Is it consider a non-impulsive force? The book we use in class describes an impulsive force in terms of certain forces acting as a very...

I will post a picture of the problem in a few hours. But to answer your question, Cylinder A is on top of B. Both are intially at rest. Mass A is released and Drops onto B. When the masses make contact, A stops and B has the kinetic energy. Hope that helps

I was reworking a problem from class today, and made a simple assumption, in regards to the problem, that made this problem much easier. My question: Is it fair to assume that the velocity of Va = Vb, after impact? The weights are non-impulsive, since the difference in weight is small. I ask...

actually I am already given \omega, that is what angular frequency is. Although just re reading my initial post, I can spot my problem. I made an algebraic error: 10(cos(90)+ j(sin(90)) + 66 - j(10) corrected: 10(0) + j(10) + 66 - j(10) which just simplifies to 66, while the imaginary cancel...

V(a)cos(\omegat+\phi)

Question: Convert V = 10< 90 degrees + 66 - j(10 V) at angular frequency = 10k rads/s. I am stuck here 10(cos(90)+ j(sin(90)) + 66 - j(10) which would then be: 0 + j + 66 - j(10)

The current in resistance i6 is 1.4A. The resistances R1 = R2 = R3 = 2.00 ohms. R4 = 16 ohms, R5 8.00 ohms and R6 = 4.00 ohms. what is the ideal voltage of the battery. https://skydrive.live.com/redir?resid=8DF4E9B990698B55!1849 Hopefully this link works.

Okay ran into another circuits issue. We have to compute the voltage of the entire circuit. I have set up my systems of equations. However for "v" I need a value. I use the rref feature in the calculator to determine currents. I am not exactly sure how to go about solving this the way I have...

I believe I found the correct way to do this. It would have helped if I was approaching the problem a different way.
