This electronics video tutorial on electrical circuit analysis provides a basic introduction into Norton's theorem and touches on Thevenin's theorem. It explains how to use Norton's theorem to calculate the current flowing through the load resistor in addition to using KVL nodal circuit analysis.

Well done sir! That is one of the best demonstration I have seen for a long time. Good use of visual and audible techniques. As a kinaesthetic learner I was able to combine what you drew on the board with your voice description. As an old engineer of 56 this took me way back to a 16 year old who was t that interested in T+N and just wanted to build exciting projects instead…. Anyway you explained it so well I actually remembered the theory and I think I would say I learnt some very useful theory. Thanks again

@kayebaron695 4 жыл бұрын

I appreciate your work! It's very intuitive-- the way you often use voltage. It may be good for folks to know how to find "I Norton" without the use of Thevenin. This circuit is actually much easier if you go about shorting points A and B (since it removes a 3 ohm resistor), doing Source Transformation on the voltage source, and adding the current sources via the Superposition Principle. I ended up with a current source of 19.5 A running through two resistors in parallel. Current division yielded "I Norton." Anyway, thanks for your work!

Thanks for the refresher ! ENJOYED your videos. Good teacher! Correct me?: You do not need (Vc-0)/6. It's just the total voltage Vc across both resistors to B, Vc/6. How you said it confused me. It's been years. For me, what would have helped me understand quicker, if you'd said, "Total" current of I1, plus "total" current of I2...I lost that back in time somewhere. We all learn and obsess (lol) differently ! Thanks again! Made the gray cells exercise again !! Broke out my pencil and paper and eraser ! Good format. Liked how your computer graphics worked. Good calm voice. And your math gymnastics. I love to see how other people learned. You taught me to see several of the formulas differently than I was taught. Enjoyed it !!

@jafarsabbagh7914 4 ай бұрын

The resistances are in parallel at 2:00 because he was calculating the resistance, but when he started to calculate the current at 4:20 the current would be the same at both positions because at A there is no current going through so the current would just continue down to B. I3 is the same at both resistances. Another way to think about it is through KCL which states that the current that goes into a node is the same amount of current going out of a node. in this case I3= 0+I4, meaning that I3=I4 so they are both basically I3.

Might be a bit late, but since I had the same question and figured it out, I thought I would share: He took the two 3ohm resistors in series and added them together, causing node A and node C to be identical. Then, since node B is the designated ground (therefore 0V), Vc/6k is the simplified result.

@@keremhassoy9556, I am not sure what you mean by this. Doing (Vb-Va)/3 would be in the incorrect current direction for this solution. Also, the calculation of (Vb-Va)/3 +Va/3 is TECHNICALLY (Vb-Va)/3 +(Va-Vb)/3; which sums to 0 since you are adding the current value across the same resistor from from both directions. Good luck!
