WOW! You are the best... i've watched a lot of videos about series and parallel connections,but still confused, fortunately, i came across this video and this really helped me a lot.. i have an exam tomorrow, and this will definitely be of great help, please continue making more videos of this kind... :)
Thanks Louise! Good luck with your exam! :-) If you have specific problems in the course, feel free to send them to me and I'll solve some in my weekly video: info@redmondphysicstutoring.com. I also have lectures for most of the course available for free at Udemy: www.udemy.com/user/scottredmond/
Kirchoff's rules apply for all circuits, even with multiple voltage sources. For the loop rule, when you cross a voltage source you add the voltage if you go from negative to positive and you subtract the voltage if you go from positive to negative. I should have some examples... 1) This video has two voltage sources and four resistors. At Vanier, E&M students were almost guaranteed to see a question just like this on a test or exam. ruclips.net/video/wNSIvuFBDPU/видео.html 2) Last week's webinar (ruclips.net/video/xko9D5rLgok/видео.html) has an example with three voltage sources. This video is 30 minutes long but the pace is more realistic (and you can always speed it up). 3) Another video with a tricky circuit with 5 unknowns and two voltage sources: ruclips.net/video/XtkXRTfRGeI/видео.html This video is only 9 minutes long because I sped up the algebra.
Struggled through a whole EM physics course without this knowledge. Now, I'm taking an upper div electronics course and in a moment of desperation on a complicated DC circuit went to RUclips. This makes everything so much easier!
Oh my god this is a life saver!! I have been so confused about this topic and watched so many videos that did not help but finally i understood it thanks to you!!!
Thank you very much!!! I am not such a fan of physics xD but when I find teachers like you make it better to learn, you made it so easy to understand :D
Very fantastic video such an extrodinary video I was struggling from 9th class to understand but i understood now in 1st year degree thank you very very much sir . Keep continuing like these videos to save students time .
That basically is a node concept. Across all points in a node the potential is same. And you identify the two same nodes on either side of the element, if they are same, they are on same potential difference and hence in parallel. I guess that's the technical explanation behind it.
Great vid! I have a question: About the statement: Any elements that share the same two colors are in parallel. Is it also true that any elements that share two OR MORE colors are in parallel, or not? Also, you should say that if a wire connects only 2 elements, and those elements have the same 2 colors, then those elements are still parallel.
Good question. At the intro physics level we never saw any elements with more than two terminals, so each element could only be connected to two wires and it was impossible for any elements to share more than two wires. If you add 3-terminal devices, such as transistors, then it's beyond what I've taught but my gut feeling is that you can't say they're always parallel. It would depend on where exactly the current is flowing at any given time, so it could change as the circuit adjusts. If a wire, say it's green, connects only two elements, then those two elements share the green wire. If they also share another wire, say it's red, then they are in series and in parallel. We can see this with a pair charged capacitors that get connected two each other. However, in that case thinking in terms of parallel and serial has often mixed students up. In my experience, at that point it was better to focus on applying Kirchoff's voltage rule when solving the problem. I hope that helps. Good luck!
Sure hope my profs are cool with me bringing colour pencils to my exams

Sir you really are the best,...btw, i just wanna ask, is Kirchhoff's rule only applicable to circuits with only one power source?,.. thank you sir
Kirchoff's rules apply for all circuits, even with multiple voltage sources. For the loop rule, when you cross a voltage source you add the voltage if you go from negative to positive and you subtract the voltage if you go from positive to negative.
I should have some examples...

no sir thank YOU for taking time out of your day to give us this information for free. greatly appreciate it. this helps a lot!
One of the most helpful video I've ever found on this topic. Thanks.
I will not be kidding if said this was the best class of my life, and 8 years ago man where have you been?!!! ❤❤❤❤❤❤❤
Amazing i was struggling with it for a couple weeks but after i found your video; boom, i get it in just 3minutes. Thanks indeed.
What an amazing video. I would love to be a teacher as efficient and helpful as this man. Got my colored pencils.
Great explanation and straightforward. Its nice that the video was not lengthy to explain something simple. Thanks!
oh my god thank you so much. i cannot stress how much you have helped me.
thank you man parallel and series resistors failed me in the exam but you just made it easy thanks again
THIS IS INCREDIBLY HELPFUL, THANK YOU SO MUCH. I am grateful you posted this. I FINALLY UNDERSTAND
Now this is more my speed. I love DC and have wired quite a few boat's electrical systems.
Thank you very much!!! I am not such a fan of physics xD but when I find teachers like you make it better to learn, you made it so easy to understand :D
Awesome! I'm so glad this was helpful to you. It wouldn't be easy to understand if you didn't put in the effort though - you rock!
watched many videos on how to identify parallel and series, by far the best one. good stuff
omg thank you. idk why but I struggled so much with this, but you made perfectly clear!

Amazing explanation. Very helpful.
Amazingggg👌🏻👌🏻👌🏻
Taking this into my physics exam tommorrow
Bro it was a really good trick thanks a lot.
what an easy way ! WOW
thanks a lot , please continue making more videos of this kind
Really helpful.
NICE. Now how to figure out voltage, current, and resistance for all resistors and resistor groups x_x
Does the direction of current contribute to the final conclusion that the circuit consists of some resistors connected in parallel, if yes , how so
I SWEAR THISS IS REALLY HELP MEE!!!! THANK YOU SO MUCHHH BRO 🤩

Yes! Exactly.
thank you man
Thaaannkkkyou soo much, this helped a lot!
good work bro
you practically saved me lol. thankyou.
if an element is not in parallel, then is it in series? As in the 2nd example, "E, R1 and R2" are in series with "R3 and R4"?
Superb explanation 👏👏👏
Thx u helped me a lot 🥰
Thanks, great help
This is genius 👏
So simple yet so effective! Why didn't they teach these at school?? Anyway, thank you so much!!
Yay! I'm glad it helped. Best of luck to you!
This was very helpful ly homie
Thanks sir
