Scenario:

You are presented with the following tasks by the company where you train. The electric network company must carry out these tasks within a specified time limit and most importantly with the highest of standards and proficiency. To prove to the company that you are the right person to work for it you must carry out these tasks with utmost efficiency and professionalism and within the specified time limit. All the tasks involve solving AC and DC networks using the theory and practical experiences you acquired in your modules. All the tasks must be handed in one report which must be clearly and professionally presented.

LO1 Apply an understanding of fundamental electrical quantities to analyse Circuits with constant voltages and currents.

Task 1

a. Apply and plot ohms law and determine the slope of an I-V curve (Refer to the lab experiment dc on ohm`s law in Appendix A).

b. Apply Kirchhoff`s voltage and current laws to analyse the circuit in the experiment (refer to lab experiment dc on Kirchhoff`s voltage and current laws in Appendix A).

c. Validate Kirchhoff`s laws against the practical results obtained in task1 b.

d. Evaluate Thevenin`s theorem through simulations and through theory (refer to lab experiment dc on Thevenin theorem and maximum power transfer in Appendix A).
