Circuit as the picture shows,with the independent current source generate current 2V1.
Need to find the admittance matrix Y.
{I1=Y11*V1+Y12*V2
I2=Y21*V1+Y22*V2
How do you figure that it is an independent current source? It seems like the current is dependent of V1, does it not?Circuit as the picture shows,with the independent current source generate current 2V1.
It is NOT an independent current generator. You should have been through analyzing circuits that have dependent sources LONG before you got to two-port networks.In a) case,set V1=0,
I2=-I1,V2=5*I2 ====>Y12=-1/5 and Y22=1/5
But in case b) V2=0,
I dont know if the indepen current generator still effect to the circuit,or it just be opened.
Please anyone help.
My fault,its a voltage-controlled dependent current source.It is NOT an independent current generator. You should have been through analyzing circuits that have dependent sources LONG before you got to two-port networks.
You simply have a circuit that has a voltage-controlled dependent current source. So set up the mesh and/or node equations that govern it.
Thanks,I got it.You have three currents coming into the top node.
Your first equation requires that the current coming out of the dependent current source be zero.
If that is the case, what does that require that V1 be?
If V1 is not zero, then (2 A/V)·V1 is not zero, right? If that's the case, then how can your first equation be valid?
