Answer / nileshvalvekar

When p f is leading means a leading current is supplied by
the system to the load.In this case load current leads the
load voltage by some angle so the phaser of voltage drop in
resistance & reactance leads the supply voltage( please
refer the phasor diagram) which causes the load voltage to
rise than the supply voltage.

NOTE:- to have a proof of this you need to see the vector
diagram of power system during lead power factor condition
