Homework Statement I am an EE in a research group and we are required to read up on some articles for the project. My chemistry knowledge is not the best so I need some assistance understanding some terminology. The article references the {001} surface of anatase TiO2. Can someone explain...

That's it! Thank you so much for your responses!

Perfect! i1 = 2.08 ia = 0.94 isc = 1.13 I wish I wasn't struggling with the second part but I am so any help there would be much appreciated as well. So with ia being 0.94, that means that the dependent voltage source is 1.88. add that to the other voltage source in series and you get...

Homework Statement The (b) circuit shown in the attached image is the Norton equivalent circuit of the (a) circuit. Find the value of the short-circuit current, isc, and Thévenin resistance, Rt. isc being the current that would flow through the two open nodes if they were shorted. The...

Hehe thank you so much! You were right on the money. When I had my professor look at my work, he noticed the v4/8ohm error but not the v5 error. Thank you for catching that. Ya, wasn't that an awesome problem? This is a homework problem in the forth week of intro to circuits. I guess this...

See attached for matrix. This is what I got but I think my polarities might be wrong. v1 = -8.91v v2 = -16.91v v3 = -14.63v v4 = 1.37v v5 = -16.23v

@The Electrician - Does the new equation that I wrote for the supernode satisfy the currents going in and out of that node or am I still missing something?

So the actual third equation or the v3 v4 supernode would be as follows. v3/8Ω + (v3 - v2)/10Ω + (v3 - v1)/5Ω + v4/8 + (v4 - v2)/4 - 2A = 0 The 16v in the supernode is take care of by the v4 - v3 = 16v equation. Is that correct?

v3/8Ω + (v3 - v2)/10Ω + (v3 - v1)/5Ω + 16v = 0 ? Also am I missing something by not incorporating the 2A source in my equations?

So would ix = (v3 - v2)10Ω + (v3 - v1)/5Ω ?

Yes sorry, I missed that when transcribing it. (v1 - v5)/2Ω + (v1 - v3)/5Ω + (v2 - v3)/10Ω + (v2 - v4)/4Ω = 0 I'm not seeing how I get the ix without doing a complete mesh current analysis of the circuit. Is that what I have to do?

Sorry, must be a login issue. Please see attached.

I apologize if I seem a bit dense but could you elaborate on your question about the expansion on cos(t)? I'm not entirely sure what you're asking.
