Homework Statement
Find IA, IB, IC, I1, I2, V0, VA
Homework Equations
The Attempt at a Solution
(V0/10) = IA-IB
For IA: 10v + 10(IA+IC) + (IA-IB)=0
11(IA) - (IB) + 10(IC) = -10v
For IB: -(IB-IA) - 20(IB+IC) - 10(IB) = 0
IA - 31(IB) - 20(IC) = 0
For IC: 10(IA+IC) - 20(IC+IB) - 10(IC) = 0
10(IA) - 20(IB) - 20(IC) = 0
I then put these equations into a matrix (Sorry I don't know how to put them into a matrix on here) and used an online matrix calculator to get the currents:
IA= -0.4A
IB=(18/55)A
IC=(-29/55)A
So then I plugged these values into this formula:
(V0/10) = IA-IB
And got V0= -7.3V
But when I used v=iR to see if I would get the same thing I got
v=(-29/55)(10)= -5.27v
What am I doing wrong?
