Nodal Analysis

For this lab, we were asked analyze a "reliable" circuit that contains multiple loads and two power supplies. We were given the values for all resistors and both power supplies. With these we calculated what our voltages were supposed to be using nodal analysis. When we finished, we needed to then make a circuit to be exactly like the one we used to calculated our voltages. With the multi-meters, we measured the voltage and current values and compared them with our calculated values.
