Homework Equations
Ohm's Law V=IR
KVL: Sum of all voltages must = 0
KCL: Sum of current going in = sum of current going out
The Attempt at a Solution
Basically we have to show the math behind the simulated circuits.
I know i have 8 unknowns in the circuit. And i think i have been able to get 8 independent equations.
I1=I2+I3
-12+V5+V2+V3+V4+4=0
4+V4+V3+V1=0
V1=8*I3
V2=3*I1
V3=5*I2
V4=I2
V5=I1
(Note: I've ignored the Batteries being labeled as V1 and V2)
We have been taught to obtain equations using Ohm's Law, KVL and KCL.
I have tried to solve these equation but am unable to.
Are these equations correct and am i on the right track?
