Matrix therory

    1. The problem statement, all variables and given/known data
    Hi,
    i need to find the Admintace matrix and the current voltage vector.
    i know how to do it if i have only non dependent sources.
    but how should i work with the dependednt source?
    s
    should i take the dependent voltage source and turn it to current source with paralel resisotor?

    thanks in advance.

    I think if you just write the node equations using the dependent sources as-is, and then write separate equations for the dependent sources (for example, [itex]V_x = \frac{e_3 - e_2}{R_x}[/itex]) that you can substitute in, then you should be able to extract the admittance matrix from the resulting equations.

    thanks,
    BTW, how can i represent Vy?...

    i think Vx is just e2-e3, no?

    What is the current through Ry?
    Why, yes it is. Well spotted :approve:

    oh..
    the currnt is alpha*Vx, so the volage Vy= alpha*Vx*Ry?
