How To Solve Any Resistors In Series and Parallel Combination Circuit Problems in Physics
This physics video tutorial explains how to solve any resistors in series and parallel combination circuit problems. The first thing you need to do is calculate the equivalent resistance of the circuit which you can use to calculate the current flowing from the battery based on ohm's law. Using the current and the voltage drops across each resistor, you can calculate the electric potential at every point in the circuit which will allow you to calculate the current flowing through any resistor. This technique is useful if there's not multiple batteries in different loops of the equation. Keep in mind, the current flowing in two resistors that are in series with each other is the same. The voltage is the same across resistors connected in parallel. This video contains plenty of examples and practice problems including a current division formula for resistors connected in parallel.

You are way better than all of my teachers From school to University None of did a better job at simplifying these topic like you. You made me realize that physics/math is easy and fun.
Umm... this was so valuable to me. I'm trying to re-learn the math and long-hand calculations from when I was in school in the 80's! Trying to pass a qualification exam. This video was a blessing to me. I'll try and update you on how well I did. Took this same test several years ago, and was completely lost. I think I'll do much better this time. Thank you.

From now onwards you're nolonger called the Organic Chemistry tutor but "The God sent tutor" Your delivery is just on point sir,much appreciated ❗❗
This is pretty random but I keep your physics videos playing whenever I feel meh about solving physics. You working through the problems step by step gives me the energy to do the same; slow down, read the question and solve carefully. Thanks for your videos man.
[EDIT 2 YEARS LATER PASSED WITH A B!] You’re going to be the reason why i’ll pass my final tomorrow, thank you so much!

man you made my basics on this topic sky-rocketing. I couldn't even solve a simple circuit now I'm able to do some circuit problems. thanks, isn't enough for you man
You know it's funny on how every time I get stuck in any subject except of Bio,you and your videos just step in and save me. You are like a super hero. Thank you very much sir,you are a life saver,not sure there Is a way to repay you.
for some reason i was never taught to redraw the circuit at all. I just watched this video and another one where you both redraw the circuit and my mind is blown omfg. it makes everything so much easier to understand

Absolutely NO redraws are necessary!. Find total resistance from right to left, back to the source voltage. Then figure the total current by Ohms law. Now, going from left to right...figure your voltage drops across R1 and R6. Then subtract those voltages from the source voltage. Divide the 15 volts by R2 resistance to get 1.5 amps, which is half of the total current. The other 1.5 amps goes thru the rest of the circuit, or just divide the 15 volts by the total resistance of the three resistors in the far right part of the circuit. Bingo, problem solved people!

For some reason this has conceptually been one of the hardest topics for me to grasp at the beginning.. thanks for helping clear it up!
I was confused as hell and then I watched your video and now I feel like a professor🤣 Thank you so much! Your videos are always great and detailed!
Man you're whoever you think you are, no youtube tutor comes close not even an inch closer the gap is too wide. See how I understood this equivalent resistance effortlessly. I've never regretted subscribing to your youtube channel and I will make sure my course mates subscribe to your channel as a form of appreciation to the amount of work you put in just to make us understand seemingly complex topics easily. Because almost all my course mates did not understand this topic when the lecturer came to deliver to the class.You'll be the reason why i will graduate with First Class. thanks once again! Gracias
your silky smooth voice and calm delivery makes understanding physics SO MUCH BETTER
I appreciate your videos so much. Just started learning RC circuits in lecture this week and I didn't understand anything, but after this video I feel so much better about solving these questions! Thank you!
I gotta test tmr fam. Last minute study gang whassup 🤣
You do such a great job explaining multiple ways to solve the same problem! In earlier lectures you showed how to do it by summing the resistors in series on right side and then solving the parallel resistors and now you explained the alternate way to solve to find the current through the middle resistor by using the potential difference between two voltage points on either side of the middle resistor and solving for the current through the middle resistor and then subtracting that current to find the remaining current flowing through the resistors in series on the right side of the circuit! Just what I needed explained clearly!

ily! You solve the problem that has been bewildering me for the whole day! My life would be much easier if I discovered your channel earlier!
im currently preparing for my jee, it was helpful your just the best at the subjects and even better at explaining than our indian teachers...❤
Im a 10th grader in Turkey! Your videos always help me before exams when im trying to digest all that information. Love you ❤

Thank you so much I like how you resolve series-parallel problem . I could not finish my homework without your video. Thanks a lot
THANK YOU for bringing physics to it's knees
Thanks so much, the vedio is so helpful.. I don't understand the lesson in class but with your help and now I can solve the questions...
I didn't understand anything at school but after this video I feel like a wise 😂😂 thank you best teacher ever.
Awesome, have watched a few of your other videos , EXCELLENT. Thank you.
Thank you bro I didn't attend class in which this was explained and i was left behind and i don't wanted to ask my teacher to explain me the whole xoncept just because i didn't attended the class you saved my life
here's a linus tech tip, continue the great work thank you
Finally, I understood it in less than a minute! Thank you!
your videos have helped me so much, thanks again for sharing your knowledge
😩been struggling heavy but sheesh boy am I glad I found this video💯
Actually very good video for all physics students
To compute 2 resistor in parallel with different value just multiply the Numerator then add the Denominator and Devide the value that you get in 15:31 minutes 12 * 4 = 48 (Numerator) then 12 + 4 = 16 therefore 48/16 = 3ohms
the best explanation, thank you!!
Great examples. Thank you!
I love ur videos and now I understand all or somethings about physics Thanks so much❤❤😊😊

In physics class, to combine parallel repressors, we have been using the formula 1/Rt =1/R1 +1/R2, but that doesn't seem to be in your video. I'm still kind of struggling to understand circuits as a whole, and it would be very helpful to me if you could explain that rule/ its relevancy to circuits. The right hand rule also has been confusing me as well. I love your videos, they've helped me loads in AP Chem and in physics. I'm really glad that there are people out there who make videos to help others, rather than click-baited videos.

You only combine them when u are trying to figure out the current encompassing the whole device (circuit). Once you do that you can troubleshoot your device with a multimeter and see where its failing you.

didiroxforever that method still applies, in the first question he did he said the total resistance for the the two ten ohm resistors in parallel was 5. He got that by adding 1/10 + 1/10 then finding the inverse of that answer
Thank you for your videos. They are very helpful.
Thank you so much, I was able to understand part where I had a mistakes.

Just saved me, have a test tomorrow on this, didn't understand a thing prior to watching this🐐❤️
indeed u made me understand it greatly with a trust to pass it come to final exams
