Power factor is the cosine of angle between the current and
the voltage

by leading power factor we mean that the current is leading
the voltage by some angle
or simply current is more than the voltage.

and when it happens there is some losses that actually
occuring in the transmission or distribution system which
will effect the efficiency of the transmission of the power
supply system.
