Lagging means current is lagging with respect to voltage by
some angle and in case of leading current leads voltage by
some angle.
in case of resistive load: current and voltage are in phase
ie angle between current and voltage is zero.
in case of inductive load:- current lag behind with respect
to voltage by some angle.
In case of capacitive load:- current lead voltage by some angle
Only remember CIVIL :- That means in case of capacitor(c)
current(I) leads with respect to voltage. similarly in case
of inductive (L)load we start from right side: current (I)
lag by some angle w.r.t to voltage.
