Nodal Analysis
Using Nodal Analysis to solve "Supernodes". By doing this we relate all voltages to a "ground" node. In doing so we can come up with a system of equations in which to solve for certain elements in the circuit. For this pre-lab we find the theoretical values of the voltage across each of the resistors.
Now it's time to test the results in our pre-lab. We will create the above circuit and measure each of the voltages across the resistors.
With Nodal Analysis we were able to find the voltages across each of the resistors with 1% or less of error. This 1% of error most likely arose from the fact that our voltages across every area were off by plus or minus 1%. For example, the voltage across the voltage source 3V was actually 2.99V. Our measuring instrument could also add a small error of uncertainty. However, this was an excellent experiment.
