Nodal Analysis Problem:

We need to calculate the Potential difference V1, V2, V3, V4, V5 using nodal analysis method:

 We make a mistake by applying nodal analysis on the reference node for our fifth equation. To fix this problem we applied Super Nodes across V1, V3 and V5 to obtain our fifth equation:

Nodal Analysis Lab

Measured resistance value using digital multimeter:

Our first attempt at setting up our Breadboard:, we used up too much ground wire:

Second Attempt at handling our breadboard, we get rid of unnecessary ground wire, since waveform have an internal ground, we connected +5V to the red wire, -5 V to the white wire, and -3 V to the yellow waveform wire:

We measured the potential difference at 10 K Ohm resistor:

We measured the potential difference at 22 K Ohm resistor:

We measured the potential difference at 6.8 K ohm resistor:

Simple Mesh Analysis with no current source :

 Mesh Analysis With Current Source; Super Mesh:

Summary:

To calculate potential difference between resistor we can apply nodal analysis on each node compared to the reference node. We can apply a mesh analysis on a planar circuit with a lot of voltage souces. When Current source exists between two non-reference nodes; we have to apply super mesh .
