I have the two node equations set up

Node A: -10 + V1/10 + (v1-v2)/(1+j56.55)=0
Node B: (v2-v1)/(1+j56.55) - v2/j299.16 + v2/5=0

I have no idea how to solve this...
help please


updated the pdf attached

 

Not sure what relevance is the attached file....?

Was it meant to show your working?

 

attached file is the actual assignment

 

Attachment looks like a set of lecture notes which seem to have no connection with your nodal equations.

 

o crap wrong attachment ill put the new one u[p

In any case you need to re-arrange the equations first by collecting the coefficients of the common variable terms (v1 & v2) into the standard form for solution.

Node A:

V1(1/10+1/(1+j56.55))-V2/(1+j56.55)=10

Node B:

-V1/(1+j56.55)+V2(1/(1+j56.55)+1/5-1/j299.16)=0

If you have Matlab or something equivalent which handles complex number matrices you can solve the two equations simultaneously for V1 & V2. Otherwise you have to do it long hand which is a fair amount of work.

 

thanks for the help, i found a way to solve it on my ti-89
