Answer / prem maheshwari

in case of leading, current leads the voltage at angle of 20,and in laging current lags behind the voltage.mathematically both have equal vallu but, phasor diag. is diffrent. frist is capacitive load second is inductive load.

Answer / najeeb khan

reactive power remains same in both cases. mathematically we
just write Legging or leading. actually reactive power is an
undesirable phenomenon whether it is legging or leading.

the reason we think that leading pf is good is that it
neutralizes the legging reactive pf,(as our power system
mostly consists of legging pf equipments ).
