Nodal Definition and 224 Threads

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...

Helping setting up Nodal Equations... Homework Statement I need to find the node voltages at N1 and N2. See attachment for circuit. The Attempt at a Solution I think I need to setup KCL at each node. At Node 1, I got this: (v1-v2)/12 - (v3-v2)/20 - (v2-0)/40 =0 v1 is the...

Circuit Nodal voltage question...please help out thanks! Homework Statement The question is as follows: Start with KCL for the nodes and write the node voltage equations for the nodes V1 and v2 in the circuit (diagram is attached to this post). They do not want me to solve the equations...

My circuit analysis professor showed us a method of nodal/mesh analysis today that allows us to write the matrix equations for either nodal/mesh analysis just by inspection of the circuit. Is anyone familiar with this method or ever heard of it? The circuits that he used this technique...

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...

A two-point source operates at a frequency of 1.0Hz to produce an interference pattern in a ripple tank. The sources are 2.5cm apart and the wavelength of the waves is 1.2 cm. Calculate the angles at which the nodal lines in the pattern are located far from the sources. (assume the angles...

Hi, I am having trouble filling out the nodal equation for the node of the first op-amp towards the left. Let's say that node voltage is Vx. (V-) I know that, Vx - 5 / 70k + ~~~~ = 0... I don't know what to put for the ~~~~ part. I know the current has to equal the current across teh 70kohm...

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...

Homework Statement http://img258.imageshack.us/img258/2152/screenshot01kf5.th.jpg Homework Equations KCL KVL V = IR The Attempt at a Solution I used 4 nodes at the top, one reference node at the bottom. I have it labeled V1, V2, V3, V4, starting from the far left -> right. My nodal...

Hi, I just have a quick question about nodal analysis in the attached file. At v1 and v3, is it not necessary to take into account the current going to the right and left respectivley? So at v1, -6V + (v1 - v2 / 6k) and at v3, 24V + (v2 - v3/4k) Thanks a lot!

Find v_1,\,v_2,\,and\,v_3 in the circuit below using nodal analysis: My work so far: I\,=\,\frac{v_1}{2\Omega},\,\,I_1\,=\,\frac{v_2}{4\Omega},\,\,I_2\,=\,\frac{v_3}{3\Omega},\,\,I_3\,=\,\frac{v_1\,-\,v_3}{6\Omega} KVL @ loop1 => -I\,(2\Omega)\,+\,10\,V\,+\,I_1(4\Omega)\,=\,0...

Hello everybody, my apologies if this is a stupid question. Under the sound (specifically vibrations and waves) unit in my textbook, it briefly mentions nodes. However, it merely describes it as a "centre point [that] always stays at the equilibrium and never vibrates." My question is...

I am trying to find the frequency response for the given circuit. My instructor recomended using a nodal analysis method. However, while attempting to use the nodal analysis I end up with all my variables equaling zero (Va = 0, Vin = 0 and Vout = 0). Is there something I'm missing or over...

Can someone direct me to a tutorial for solving network nodal voltages. Also need to learn how to convert voltage source to a current source.

Hello, New to chemistry need help with this question and I don't understand what a nodal surface is How mnay nodal surfaces are there for a) a 2s orbital b) a 3px orbital If anyone can help me that would be great. Thank you

Ok here's the problem: Waves are produced by two point sources S and S' vibrating in phase. SEe the accompanying diagram. X is apoint on the second nodal line. The path difference SX - S'X is 4.5cm The wavelength of the waves is approxiately______. ````` o X ``````| ``````| ``````|...

Hey just need a quick clarification here. I am reading conflicting arguments. One argument states that to find the nodal surfaces of an orbital you take the result of n-1 the other argument states that the number of nodal surfaces of an orbital is equal to n. Can someone please clear this...

nodal voltage?? im not real sure on how solve circuits using the nodal method. I've got an equation for node a but i don't know how to solve it. here's the equation (90-Va)/20 - (Vb-Va)/3 + Va/20 - Ia = 0 thats at node a. how do i solve this? Ia = 6 A

I am wondering what forces cause the nodes between orbitals to occur, and if these nodes are ever penetrated or crossed by electrons during exitation of the atom.
