Nodal analysis

Objective: 

      Learn more nodal analysis and how KCL can become a very powerful tool when solving circuits with several resistors in parallel. 

Step one: 

set the up the following circuit, Calculations for step one: 

Table of values

We set up the circuit and now compare the power

Next the requirements are that 9v=v2=v3 so this is what we would get 

Observations

The actual power is pretty close to the values we found at the beginning of the lab.
