Homework Statement Homework Equations KCL The Attempt at a Solution I recognise that the voltage sources form supernodes. This produces: A - B = 10 -> A = 10 + B We also know that node C is 12v. I then form KCL equations: 6 + \frac{A - C}{12} = \frac{B}{40} + \frac {A}{24} When I...

The question might be simple for you guys but the problem is that it is not for ME ! I have a circuit and I have to determine the node voltages by Nodal Analysis method. And the one which I learned was in cases when we had a current source, I could simply write the equations using KCL...

Homework Statement I have to solve for V0 , using nodal analysis. I am getting different answers in MATLAB and PSPICE. The circuit is below 2 supernodes ; or 1 big supernode Here are my nodal equations: v1-v3 = 12 v3 - v2 = 6 (v3)/6k + (v1)/4k - 6/k = 0 Matlab output is here...

Homework Statement I am having some trouble with the nodal analysis algorithm explained in this web page http://www.swarthmore.edu/NatSci/echeeve1/Ref/mna/MNA3.html My electrical circuits knowledge is very basic, and I need to get the equivalent resistance of a circuit for a non related...

Hi, I would be grateful of any advice on how to solve the problem below. My aim is to find the voltages at nodes 2, 3, and 4, by means nodal analysis and thus creating simultaneous equations and solving them using matricies or matrix in order to prove that these theories work. I...

Hi, I am just beginning to learn about op amps and I was wondering if there was a way to use the node voltage method (nodal analysis to some) to solve these circuit without replacing the op amp with its equivalent ideal amplifier. To me, it is much faster to use node voltage method than going...

Homework Statement Find v1 and v2 from the given picture. Homework Equations Ohm's law, V=IR Current Division The Attempt at a Solution I tried to use current division. The 6A source split into 2, giving 2A down the 8 ohm resistor and 4 amperes down the 4 ohm resistor. Since...

Guys l would like to know how does the the voltage at node D become : Vd=-(Vc-Va)=Va-Vc

http://i615.photobucket.com/albums/tt237/chaz0426/Problem2.jpg it asks to solve for V1 and V2 using nodal analysis however I'm not sure how to solve this particular one because there is a voltage source and a resistor between the reference node and V1and I'm not sure what to do. Here is what...

Hi, I was wondering if it's possible to solve nodal analysis problems that include rectangle and polar form using the TI-84. It just gives me an error when I put in "i" as in imaginary when trying to put up my matrix. I've read it's possible to do with the TI-89, but I'd really rather not...

Can someone solve this circuit Find v and i in the circuit. I know that we have to make somethng with supernode, but where the supernode is here? How to develop this problem? Please help me :) Btw it is nice forum, today i have found that. I hope I will be able to help you in other...

Homework Statement Consider the circuit shown (attached). Calculate the voltage v and calculate the power for the 2A current source. In this particular case, is it supplying or absorbing power? Homework Equations The Attempt at a Solution I know that there is 2A flowing around...

Hey guys. I have attached a circuit that i am trying to analyse using nodal analysis. This is how i am doing it: at node 2: (v2-v1)/1 + v2/4 + (v2-v3)/1 = 0 at node 3: (v3-v2)/1 + v3/2 = 4A at node 1: v1/25 = 2A but i am not getting the right results for v1, v2 and v3. Can...

I've got a small issue at hand right now. I need to solve simultaneous equations with unknowns in order to do mesh and nodal analysis problems. The issue is, i can't figure out how to enter the equations into get an answer out. My previous calculator was a t183+, so I'm not that well...

Homework Statement i haVE tried to solve it no. of ways but i didn't get the right answer. Please have a look on the question 1(b) in attachment Figure 1(a), I want to know that how can i solve this question by using nodal analysis. Please explain your answer as well so i could clear my...

Could u guys reccomend some e books for loop and nodal analysis . I am having some problems implenting the methods to solve poblems. or may be u could give me some tips

I really need to learn how to do "Nodal Analysis by Inspection" before Wednesday! My Prof. told us (very quickly) about some easy method for circuit analysis called "Inspection". Can someone explain, in detail, how this is done? If you want a circuit to demonstrate on, just check my old posts...

Homework Statement Hi guys, I solved this problem out. I'm just curious as to see if my work is valid. I strongly believe it is, but perhaps you can help me. I do have a quick question... once I've found all the voltages at specific nodes, I_o is the difference of the voltage / resistance...
