Equivalent Resistance of a Complex Circuit with Series and Parallel Resistors

This tutorial goes over an example finding the equivalent resistance of a complex circuit with many series and parallel resistors. We just need to go through methodically one step at a time, recognizing small sections that are simple series or simple parallel between two nodes, and reduce those sections to equivalent resistors, and then iterating again.

This video is part of a full free course on electric circuits. The course covers DC circuits, circuit laws, current & voltage sources, series & parallel resistors, nodal analysis, mesh analysis, and AC circuits.

Thanks for watching 🙌

You've earned a special place in heaven with the invention of the node coloring!

[chrispatmatbuilds]

I'd never seen the node coloring before. Absolutely blew my mind when you did it! I'll be using this from now on!

[Mac_TO]

Thank you for simplifying the lesson so well.
One needs not see another lesson on how to calculate complex resistors.

[BallisticWof]

This helped so much, I had no idea how to figure out which were parallel or in series in a complex network of resistors until this video.

Tomorrow is my Mid Exam at University.
It's Very Helpful For me. thank you Teacher

[pessimisticcatto]

well explained in a creative manner! it was so satisfying for me to see the resistors get smaller in quantity :))

[jiayi]

Ok now make a part two showing how to find the current and voltage for each resistor PLEASE

[mashrafimorshed]

This circuit up there was really amazing. Though my answer was wrong, I was close. Thank you.

[olissvans]

Would've loved to find this a year ago. Made something so complex look easy.

[CoolyCools]

i wouldnt have done my homework without this thanks mister

[ezatali]

Thank you it helped a lot, could you please make a video finding the current in each of this resisters?

[tacia]

Learnt more from this video than I did in class

[artistic.harman]

bro ate the whole circuit haha btw thanks :)

[tom]

i wish my life could be unraveled this way

[zerowolf]

I'm just confused on where to draw the resisters after you add them

[soothingsounds]

Please make a video on Norton's theorem and Thevenin's theorem

[ziggycabs]

0:50 - This is the one I was looking for! The formula lol! Even though I already did go through all of these before, forgetting how to calculate and the formula behind it was and will be my biggest problem lol! My memory is not that good enough to recall this one. So watching this part helps me a lot for a forgetful person like me lol! Thanks anyway!

[letsstudy]

It was litteraly very easy for me (tenth grader)

[kisalaykarnsingh]

For me It is the best and most interesting numerical for class 10 physics lover
