The multiple explanations for sign convention seemed self-contradictory at times. I think of it as passive = no energy being used = rolling down a voltage hill as opposed to climbing up. However, I'm not sure if this train of thought has correct energy and power implications. More explanation would be helpful.
I think I started to understand the sign conventions towards the end of the video but would benefit greatly from doing some practice with them in class
I think for the most part I understand passive sign convention, though I do think that some practice in class would be helpful. I also would like to review the concepts regarding absorbing and delivering power.
From what I understand if current travels into the + terminal and out of the - one, we have power absorbed. If current comes out of the + terminal and into the - terminal we have power delivered.
I feel like I understand sign convention. However, although I can identify the signs when power is absorbed/delivered, I'm not confident in my understanding of why.
I would like to go over passive sign convention and the difference between passive and active. I felt like I understood it at times but then was lost again on a different example.
Hi DK, I could not find a place to write comments for lecture #2 but I had a question about it. WHy (in example #1) were the arrows going opposite direction? I thought for Kirchhoff laws there needed to be a closed loop.
I do not fully understand passive sign convention or its purpose and would like to discuss it further in class.
ReplyDeleteOk.. Will do. --DK

ReplyDeleteOk. We'll discuss in class. --DK
DeleteIf we could briefly go over the passive vs. active sign convention in class a little more that would be great.
ReplyDeleteI would like to go over the passive and active sign conventions a little more in class. I get the idea of it, but I have trouble doing them.

ReplyDeletePretty much the same as everyone else; further explanation on sign convention would be helpful.

ReplyDeleteYes! Excellent!

ReplyDeleteOk. No worries. We'll work on it.

ReplyDeleteFor example two, don't the resistors need polarities?
ReplyDeleteHmm. Not necessarily. But we can certainly discuss it.

No worries. I wilol let you know in lecture in class i you need to Blog.
DeleteWas the explanation in class about the arrows ok?
