Objective

         The objective of this lab was to compare the theoretical values of our mesh analysis vs the  measurements of a specific circuit. In place of a single 20k resistor, two 10k resistors were run in series.

Procedure
       There were three different circuits to be setup
       pt.1

       Part one required a measurement across the 6.8k and the 20k resistor.

       pt.2

       Part two required voltage measurement across the 6.8 k resistor as well as the current through the branch.

    pt.3 



       Part three required a measurement across the voltage across the 20k resistor as well as the current though that branch.

Calculations

     *Each circuit was solved by means of MatLab and Mesh analysis by inspection

Conclusion

       Solving these circutis with either mesh or nodal gave me the same answer but I decided to check the results by using fremat and setting up a matrix my inspection.
