I don't entirely understand how to deal with the polarity marks, but I've tried switching plus and minus for the j24Ω term. It's my understanding that they should both be -j24Ω, multiplied by I1 or I2 respectively, but I've tried both minus, both plus, one minus, one plus, the other way around...

Mesh 2: (600@-30deg) + 30(I2 - I1) + j50(I2) + 80(I2) - j24(I1) = 0 How else can I demonstrate? It's there. If you mean how did I mix polar notation with rectangular notation, I punched it all into the TI-89, in which the modes were set to degree, polar, and approximate. Otherwise, I don't...

Phasor Mesh Current--what am I doing wrong?? Homework Statement Circuit diagram: Calculate the phasor mesh currents, I1 and I2. Homework Equations KVL/Mesh Current analysis with phasors/complex numbers. The Attempt at a Solution Mesh 1: (-550@0deg) + j75(I1) + 30(I1 - I2) -...

Yeeeeeep that did it. lol. The overwhelming majority of my tutoring problems lately have been someone else going "fix this <fill in overly simple tiny mistake that derails the whole damn problem> and you're good". Thanks again. So I don't have to include the 120V source in the equations, and...

GAAAAHHH! Now I've got another one--that other one that I mentioned--except I'm not sure that I have the right approach for part of it. It's another one listed as a mesh current problem. Circuit: Problem: Find iy, io, and vx. General approach: Clockwise supermesh around the top two...

*ahem*...[SIZE="1"]it worked this time. Thank you for being the invaluable second mind and second set of eyes. After I realized what you were saying, that I was trying to break Ohm's law, I realized I was doing the same thing in another problem. OOPS. So glad these are just extra...

I now see. I was trying to say that I = I*R, which is, for all intents and purposes, bull. lol...*sigh* I'll post back with the result either way. Thanks again..

Okay, well, still no dice, and I still don't see what I'm doing wrong, especially with taking what should be the correct approach with the dependent source. The original problem is above, so I'm going to type out my latest attempt. There were two versions of it, because an approximation was...

Nope. Perhaps I'm taking the right approach now, but I'm still getting it wrong. I think before I post my new attempts, I'm going to go eat supper, go to my night class, and come back with a (hopefully) fresher mind that isn't low on blood sugar.

...and therefore I2 = -4ix, and my set of equations must reflect that accordingly, right? ah HA! Thanks! EDIT: ...aaaaand I2 therefore is a forced mesh that needs no equation of its own! derpa herp derp...lol. Whoops. Again, thanks.

Mesh Current: Cannot see my mistake in my approach? Homework Statement Find currents I1, I2, and I3 using Mesh Current Analysis in this circuit: Homework Equations KVL The Attempt at a Solution Initial equations: Mesh 1: -120 + 20k(I1) + 40k(I1 - I2) = 0 Mesh 2: 40k(I2 -...
