I need to get 7 equations to make a 7x7 matrix in order to solve it. I have 4 of them, but I'm not sure how to get the voltages equations.
The Attempt at a Solution
I have got four equations so far. One is simply using KCL, I1 = I2 + I3 + I4. The other three are from using KVL and Ohm's Law to get:
1. V0 - VR1 - VR4 = 0
2. VR4 - VR2 - VR5 = 0
3.VR5 - VR3 - VR6 = 0
Applying Ohm's Law:
1. V0 - R1i1 - R4i2 = 0
2. R4i2 - R2(i3 + i4) - R5i3 = 0
3. R5i3 - R3i4 - R6i4 = 0
How do I get 3 equations for the unknown voltages?
