Thank you so much for the help. Your reply explains the solution really well.

I understand that part with no difficulties. It explains the first step in which point rc is denoted. It's just the second stage that I'm not seeing clearly. It looks like a(0, -sin\theta, cos\theta) is arrived at by differentiation of rc, but I cannot make the connection between doing that and...

I've been looking at my electromagnetism lecture notes I have been given and am trying to make sense of a step made in parameterising a current loop. I am really confused about the part where dl is first state. I have no idea how the 0, sine and cosine got there. I suspect that it's something...

Thanks a lot for resolving this issue and helping me to understand this concept. It seems like the textbook I'm using skips over the finer points and implications of Thevenin's theorem somewhat. The one example given is quite a bit easier than some of the questions, which doesn't help much.

I completely understand what I did wrong now. Thanks a lot. I think I'll be okay with Thevenin's theorem problems now =] Just one last thing. You say that "you should redraw this portion with the V_th* as a voltage source." I'm a little confused about what you mean by this. Do you mean that...

Thank you for your invaluable advice. I've been doing the problem above, for which I have the answers RTh and VTh values given. Using the method you have outlined, I get the correct answer for RTh, but double the correct answer for VTh when I use the potential divider equation! I encounter...

Here's another question, attached below. Initially I was very confused by this. The only reason I have a clue about how to do this is because I've seen a similar example before. What I have so far is as follows. After the 50 Ohm resistor is removed, the infinite resistance between A and B...

Wow, I think I understand this solution now. Thanks a lot for your help. I've got a few other Thevenin's theorem questions that I'm a bit confused about that I might post later on. Thanks.

So, using the voltage divider equation, it is found that the Thevenin voltage is 5V. Is this correct? Also, for the calculation of the Thevenin resistance, using your method we must disregard the 50 Ohm resistor and add the 150 Ohm and 300 Ohm resistor in parallel? I did this and got 100 Ohms...

I'm somewhat confused by the fact that you've said that my method for working out the Thevenin resistance - adding the 300 Ohm and 150 Ohm resistors in parallel and then adding the equivalent resistance in series with the 50 Ohm resistor - is correct, but have also said that the 300 Ohm and 150...

Hey, I am wondering whether someone could help me with this question, attached below as an image. For some reason electronics has always been something I find difficult to comprehend and I have some deep misunderstandings, so I'm trying to work hard on the subject for my degree. My current...
