A load has impedance ZL 30 j40 ohm An additional component

A load has impedance Z_L = 30 + j40 ohm. An additional component is added in parallel across Z. 1 order to correct the power factor to Which of the following describes this additional component? (i) An inductor with reactance -40 ohm (ii) A capacitor with reactance -40 ohm (iii) An inductor with reactance 16 m ohm (iv) A capacitor with reactance -16 m ohm (v) An inductor with reactance 62.5 ohm (vi) A capacitor with reactance -62.5 ohm Why do we want to improve the power factor? (i) To improve efficiency by reducing average power in the load (ii) To improve efficiency by reducing reactive power in the load (iii) To get maximum power transferred from the source to the load (iv) To improve efficiency by increasing the real power in the load

Solution

d) Increase in power factor will Improve the effiiciency by reducing the Reactive power in the load and reduces utiliti bill
