Answer / shahulsnfa
in lagging PF the load will consume more current to provide
the power required by the load. the voltage remains the
same and current varies w.r.t PF.

Answer / ikab
PF lagging means there is an inductive load connected along with active load. more inductive load or less pf means more current in conductor which results copper losses and generates heat. with temperature increase resistance of a conductor would also increase hence voltage drop as a result. so Increasing voltage will result in more current.
