Answer #1

a) we know septjo P= true average powel in walle o= apparent powel in OVAR s=horal Powel in va + sign for lagging power factowe know - reactor powel = 600 VAR at drops I2x2=600 - unity power factor entire voltage at resistor ie; Up=80v PR=600 ve = 60Now PR=600w I?R=600 I? (10.667)-600 I? 56-25 so from O local. E I?XL=600 (56.25$=600 XL = 600 - 56.25 XL=10.667 Wh =10.667 Gi
