Task Introduction -

You are a consultant electrical engineer. You have been asked by your line manager, Mithun, to analyse a series of AC networks and document your findings in a technical report.

Task 1 -

Part 1 - For the circuit below using Theveins theorem, determine:

(a) The value of R to provide maximum power to the load.

(b) The maximum power transferred in the load.

Part 2 - For the network shown below determine the current with phase angle and power dissipated in the load connected between A and B using Nortons transformation theorem.

Opportunity for Merit - Repeat Task 1 (Part1 and Part2) using an alternative circuit theorem. M1

Task 2 -

For the network below, show correct method of analysis in an attempt to determine the magnitude and phase angle of the currents I₁, I₂ and I₃ using one of the following circuit analysis theorems.

• Nodal
• Mesh
• Superposition

Opportunity for Merit - Produce the same results for Task 2 using all three methods with a high degree of accuracy.

Opportunity for Distinction - Provide a table of results like the one below including simulated together with an explanation of any discrepancies D1
