    Helping setting up Nodal Equations

    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...

    Nodal & Mesh Matrix Equations By Inspection.

    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

    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...

    Angles of Nodal Lines (Two point light source)

    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...

    How Does Nodal Analysis Affect Voltage Distribution in Circuits?

    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!

    Nodal Points in Sound: Significance Explained

    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...

    Determining Frequency Response Using Nodal Analysis

    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...

    Understanding Nodal Surfaces: How Many are There in an Orbital?

    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...

    Solving Circuits with the Nodal Method: Finding Va

    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

    What Causes and Crosses Orbital Nodal Forces?

    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.
