The resonance frequency of a series resonance circuit is

$w=\frac{1}{\sqrt{LC}}$

L=8mH=8×10^-3H and C=20uF=20×10^-6F

So w=2500 rad/s

At resonance the capacitive and inductive voltages cancel out each other,ie,V_L=-V_C.

so V_supply=V_R+V_L+V_C=V_R

so current through the resistance

I_R=V_R/R=V_supply/R =220/44=5.5A

Hope this helps
