1. The problem statement, all variables and given/known data
Determine the Voltage across Resistor R6. 2. Relevant equations KVL 3. The attempt at a solution I called the bottom left Loop I1, the bottom right I2 and the top I3. All currents are flowing clockwise. From there I set up my KVL expressions for each loop: 12 + 5600(I1I3) + 5600(I1I2) + 5600(I1) = 0 5600(I2I1) + 5600(I2I3) + 5600(I2) + 5600(I2) = 0 5600(I3I1) + 5600(I3) + 5600(I3I2) = 0 From there I simplified those equations into these: I1(16800) + I2(5600) + I3(5600) = 12 I1(5600) + I2(22400) + I3(5600) = 0 I1(5600) + I2(5600) + I3(16800) = 0 Plugging the Matrices into my calculator I end up with: I1 = 9.82A I2 = 3.57A I3 = 4.46A I checked the answers and ended up getting 120008 = 12 for the first equation, 0 = 0 for the second and 56 = 0 for the third. Obviously I did something wrong, but hell if I know where. I've done Mesh many, many times before and this particular problem is just a prelab thing for a simulation but something is wrong and I just don't know what. If anyone can help me out here I would greatly appreciate it! Kevin EDIT NEVERMIND! I decided to solve it out by hand and noticed I got the exact same answers just x10^{4} and plugged them in my calculator again... turns out I couldn't be assed into scrolling to the side to see the E4 after those numbers. WHOOPS!
