I have attached a picture of a circuit. I am trying to find the values of I1, I2, and I3. What I have come up with so far, using Kirchhoff's Voltage and Junction Laws is:
I2=I1+I3
for the left loop:
9V - (5 ohms)I1 -4V - (10 ohms)I2 = 0
which simplifies to:
1V - (1 ohm)I1 - (2 ohms)I2 = 0
for the right loop:
14V - (10 ohms)I3 -4V - (10 ohms)I2 = 0
which simplifies to:
1V - (1 ohm)I3 - (1 ohm)I2 = 0
I am pretty certain that I have these correct, but I can't seem to solve my system of equations--whenever I try to add or subtract the equations, several terms cancel, leaving me with a current equaling zero.
I would really appreciate some help. Thank you. :!)
