QUESTION 3 [19 Marks] 3.1 Find the load impedance in Figure below for maximum power to the load. Show all the diagrams. Z₁ =j9 and Z₂ = 8 (9) 3.2 Determine the voltage across the load impedance using voltage divider rule if the supply voltage is 10<0 V (5) (5) 3.3 Determine the Maximum Power for this circuit 1 Z₁ 7.Th N Z₁ N Z2 Figure 3: Circuit for question 3 QUESTION 4 [21 Marks] 4. A 300kVA transformer is at full load with an overall power factor of 0.71 lagging. The power factor is improved by adding capacitors in parallel with the transformer until the overall power factor becomes 0.990 lagging. Determine the rating (in kilovars) of the capacitors required. (15) (4) (2) 4.1. Explain, what is the power factor correction and its main aim? 4.2. Explain, when will the current drawn from the supply be at minimum?
