This video helped me understanding things that were supposedly obvious but weren't so. Thank you very much for this and your other videos. They are great because you don't skip the "obvious" and state everything clearly, which helps understand every concept you're teaching. Seems you and your team put a lot of thought in them. Thanks for making them public. As a student, I appreciate it very much.
Thank you so much! You explained the concept very clearly and concisely. I read and watched many sources on passive sign convention, and your video was the only source that helped me understand!
wish i watched this vid before the midterm. I got all confused in the exam and didnt know what to pick. Your video helped me a lot now that I'm taking the course again :D thanks!
Spring 2016 Circuits student here. So basically step 1) *draw arrows parallel to each passive element in the circuit?* rule 1) current always enters positive voltage terminal
most salient explanation I've heard of these rules. Thank you! I'm curious though... While I understand that a passive element is autonomous and the math works out if I consider current in one direction for one element , and the opposite direction for the next one in a series, however... why would anyone WANT to do that? Isn't it much cleaner and simpler to think about if you ensure that current flows in the same direction as your current/voltage source(s) ?
Once you use numbers to calculate what i1 has to be you’d see that it equals -i2. Then since i2 would be negative you’d then know you have to switch the polarity of v2.
One perfectly clear 8 minute video clears up a week of textbook confusion! Amazing, isn't it?!!!
second year ENG student. youtube got me straight A's last year (with the exception of my discrete math course..c+ lmao)
you have to go through hell first to appreciate the nature of things.
yes!

A week of textbook? Dude ur just dumb
This video helped out quite a bit. My book confused the crap out of me.

These videos really just so great. Thank you guys for putting them up. Simpler and clearer than both my professor and textbook.

This was great. I didn't know that passive circuit elements could have current going in opposite directions.
Your video is very helpful. Helped me understand the lesson more. I am a student from Thailand Thank you very much.

Bilge YAĞ I have my first midterm after 7 days

Your explanation is straight to the point. Very powerful explanations.
Sir your teaching is excellent. Thanks from Pakistan
Excellent and simple explanation!
thanks for saving me from 3 days of polarity confusion trauma

Thanks very clear and well explained !
Your videos are Awsome! Really helped me!! 👏👏
Thanks my teacher said in about 20 seconds that we were gonna use this and then didn't explain it at all.

In 6:11 how can we have two currents i1 and i2 and different polarities for the nearby elements?
Once you use numbers to calculate what i1 has to be you’d see that it equals -i2. Then since i2 would be negative you’d then know you have to switch the polarity of v2.
Excellent clarification !
Great video. Thank you.
Did you have to make the current for I4 go down because the current was defined with that 0.5A
Very clear! Thanks
Goodness gravy thank you so much
Excellent
explanation in perfect simplicity. thank for that..
thanks it is helpful
So useful
👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻 well done
brilliant
7:04 I feel like I get a big slap on my face because tbh, I wastes so much time on the sign when I was doing my assigments
