Answer Posted / pradyumna chandra panda
Current leg or lead behind or ahead the voltage from maximum value ( from 90°) of alternative Qnty is called legging or leading power factor which is equal to rest valve ( 90° - legg / + lead) of sine ie. legging 36° of cose value ( .8 ) is equal to rest value of sine 54° (90°-36°) ie .8 Therfore we indirectly use sine value by appling cose value. Is this correct ? plz give your openion.
