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
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.

ReplyDeleteOk. No worries. We'll work on it.
DeleteHmm. Not necessarily. But we can certainly discuss it.
ReplyDeleteNo worries. I wilol let you know in lecture in class i you need to Blog.
ReplyDeleteWas the explanation in class about the arrows ok?
