Anninster Posted May 13, 2016 Share Posted May 13, 2016 why does mesh current law does not hold on the following circuit plz tell me fast Link to comment Share on other sites More sharing options...
studiot Posted May 13, 2016 Share Posted May 13, 2016 (edited) why does mesh current law does not hold on the following circuit plz tell me fast Because you have done something incorrect? But I see no working to comment on. Of course, the question arises, which mesh current law are you trying to use? There are several versions. Most problems arise when folks try to mix'n'match methods, which you can't do. Edited May 13, 2016 by studiot Link to comment Share on other sites More sharing options...
kisai Posted May 13, 2016 Share Posted May 13, 2016 Your mesh circuit is reporting every amperage as positive. The sum of the currents entering a node is equal to the sum of the currents leaving. Some quick adding shows me that this holds for the center line. Link to comment Share on other sites More sharing options...
Anninster Posted May 14, 2016 Author Share Posted May 14, 2016 my teacher told me to find two circuits that work with this method and every i try does not Link to comment Share on other sites More sharing options...
studiot Posted May 16, 2016 Share Posted May 16, 2016 my teacher told me to find two circuits that work with this method and every i try does not So was that a reply to my request for your calculations? We do not do your homework for you, but it is clear you have not understood mesh analysis so If you are still interested I will post one of my rough guides to help you. This will include a couple of simple worked examples. Over to you. Link to comment Share on other sites More sharing options...

This will include a couple of simple worked examples. Over to you. im not asking for help with my homework im just asking that this was just lab task that my teacher gave us but it would not hold like we can take four loops but that makes it hard in calculating the 4x4 matrix this method gives us a 3x3 matrix like on large loop and two small if you find the equations and solve them the will clearly be wrong as you can see the current in R6 and R7 ar different but same current flows through it according to our speculations so why does this method fails for some circuits Edited May 16, 2016 by Anninster Link to comment Share on other sites More sharing options...
studiot Posted May 16, 2016 Share Posted May 16, 2016 Since you know it all, but are unwilling to enlighten us, I can only say that I am sorry you cannot make it 'work', whatever you mean by that. I can only repeat my first response. The mesh method is a very general method that always allows analysis. So you must have applied it incorrectly. But since you won't tell us what you have done, I can't comment. Link to comment Share on other sites More sharing options...
