Lagging pf-the inductive power can be generated the lagging
pf.due to the copper loss in windings..

Leading pf-the capacitive power can be generated the
leading pf.due to the leading current..

Answer / sachin b. bhoir

when the load is inductive then the power factor is lagging
and when the load is capacitive then the PF is leading. in
that case of lagging the current lag behind the voltage and
in other case the current leads the voltage. The power
consumption does not effected by the PF but the rating of
the eqpt. are generally effected with pf bcoz it has to
utilised under the capacity due to low pf.
the pf can be improved by connecting the capacitor of
particular capacity depends upon your load rating to
compensate the reactive load.

Answer / sumanth kumar b

LETS CONSIDER VOLTAGE AS A REFERENCE THEN IF THE LOAD IS INDUCTIVE THEN THE CURRENT LAGS BY 90 DEGREES WITH RESPECT TO VOLTAGE.THE INDUCTIVE REACTANCE XL=J2*PI*F*L BY THIS WE CAN SAY IT AS LAGGING.
IF LOAD IS CAPACITANCE THEN THE CURRENT IS LEADING BY 90 DEGREES W.R.T VOLTAGE CAPACITIVE REACTANCE XC= IS 1/2*PI*F*C
