    Engineering AC circuit analysis -- mesh and nodal

    Ahhhhhh how frustrating! Haha I was soo bloody close albeit for one final mistake. That has had me stumped for the last few days thank you very much for the guidance

    Engineering AC circuit analysis -- mesh and nodal

    Hi gneill, I am still struggling with this, I calculated back as you said and ended up with a node voltage that of -86.3754311 + j45.7609738. I am still struggling to get the real term based on current circuit values given for the question. I end up with 67.07106781+j30 = (300-j20V/400) which...

    Engineering AC circuit analysis -- mesh and nodal

    For the Mesh analysis I end up with and answer for I = -9.152 + j17.275 this was calculated from I1-I2 From the complex matrix ((16.8117-j22.8805)-(25.9639-j40.1559)) all mesh analysis was done in a clockwise direction. For Nodal analysis I simplified down and ended up with a result of...

    Engineering AC circuit analysis -- mesh and nodal

    Hi guys don't want to sound silly but for the mesh and Nodal analysis answers for current I have the real part is identical yet the imaginary j current value looks to be off by about 1. I have used the spreadsheet shown in earlier posts for my mesh analysis and for the latter nodal I am sure is...

    Engineering AC circuit analysis -- mesh and nodal

    Hi Gneill, can you recommend any good reading material on AC circuit nodal circuit analysis with complex numbers? I have been trawling the net searching for examples incorporating the super node as in part b) but have yet to find anything! I would like to try and fully understand the method...

    Solve Superposition Theorem Homework: 50Ω Load

    Hi gneill, Please find attached my working for superposition where I end up with an answer of 5.726421015 + j1.12310464 A. I must be doing something incorrect in my calculations as I end up with a different answer for Thevenin, Superposition and Norton haha :/ any help is much appreciated!

    Solve Superposition Theorem Homework: 50Ω Load

    Hi Guys, I am not going to lie I am stuck! I have followed numerous different methods now and still coming up with the closest answer of 5.617919153+j1.37425425A. I have also been using the method from http://www.electronics-tutorials.ws for both Thevenin and Norton equivalents. Also...
