Hi. Thanks for all your help. I have now solved for I as follows: mesh 1: 120-I1(2-j5)+I2(-j5)=0 mesh 2: -14.14-j14.14-I2(-j)+I1(-j5)+I3(j4)=0 mesh 3: -j120-I3(4+j4)+I2(j4)=0 Multiplying (2) by (4+j4) and (3) by (j4) -j113.12-I2(4-j4)+I1(20-j20)+I3(-16+j16)=0 equation (2A)...

Hello again. gneill V3 = 20 <45 = 14.14 + j14.14 V3 is going anticlockwise and I2 clockwise hence -V3 = -(14.14+j14.14) = -14.14-j14.14 right ? scottdave I completely forgot about converting back to polar form. Thanks for your input guys.

Thanks for your response gneill. I've seen the above link previously that;s why I doubted my above equations as they are different so is my whole calculation which is as follows: Multiplying eq(2) by 4+j4 and eq(3) by j4 -113.12-I2(4-j4)+I1(20-j20)+I3(-16+j16)=0 new eq(2)...

Homework Statement Hi guys I'm doing the mesh analysis of AC circuit and looking for some guidance. Here is the mesh picture and some components data: Homework Equations Kirchoff's voltage law and current law.The Attempt at a Solution I decided that mesh currents are going in clockwise...

Good morning Everyone (if European time) Thanking you kindly for your help. I can see the solution is relatively easy. I now plotted my graph using Excel. BvU seems that you missed v5 phase shift. for v3 I used =SIN(3*A3*PI()/180)*28.29 , =SIN(A3*PI()/60)*28.29 works fine too. for v5 I used...

Homework Statement Hello everyone, I am currently experiencing a problem plotting harmonics in Excel. I'm only able to plot the fundamental wave properly, I can't figure out how to plot the 3rd and 5th harmonic as they have a different frequency. Can you point me in the right direction...
