Discussion
The experiment was conducted in a manner that it allowed for both of the nodal circuit and mesh circuit methods of calculations to be used. The calculations methods here were Ohm’s law of current analysis and the Kirchhoff’s voltage analyses technique. There is no circuit that does not apply the methods of Ohm’s current law and Kirchhoff’s voltage law. From this principle, we realized that we could work with complex circuits as well. Hence, we are able to do works of designing very well. We also came up with equations which we solved using the basic mathematical formulas such as Cramer rule. When confirming the calculated values with those measured using the necessary measuring equipment of measuring some differences was found in the values. These differences can be attributed to the issue of measuring errors that are usually common when humans are conducting experiments. The sources of errors in the circuit generally were due to the issue of reading and improper connections of the reading equipment leads to the circuit. Some of the values of read from the voltmeter were, however, tallying correctly with those calculated. The errors for table one were as below:
For R1.165-2=0.165ohms, %error= 0.165/2*100=8.25%.
For R2, 0.98-1=-0.02ohms, %error=-0.02/1*100=2%.
For R3, 3.253-3=0.253ohms, %error=0.253/3*100=8.4333%.
Conclusion
In conclusion, the experiment was successful as everything went as it was planned for. To begin with, there were no technical hitches to mess up with the experiment when being carried out.

Users of analog instruments may have contributed to the difference between the measured and the calculated values. However, the nodal and the mesh analyses were both conducted very successfully. The errors can be explained easily as they are also calculated in the above discussion.
