power factor in rlc ckt

sir,
in a series rlc ckt how i can improve power factor .

AT resonance, the circuit looks just like r, i.e. it will have a p.f. of 1.0

but one book suggest add capacitor parallel to the circuit for improve power factor of series lcr may you explain the reason

Yes, if the RLC circuit has an inductive impedance. You can calculate yourself. It's simple AC network calculation.
