View Answer 9 -17 Explanation:- Answer : B Discuss it below : Said on 2018-09-11 11:24:59 Supply voltage is constant and exciting current is increased so E >V means overexcited and current leads the voltage and pf decreased I think .. Piyush Said on 2017-09-24 05:49:26 I think option A is correct,please correct me if I m wrong... !!
