When the frequency of the AC source in an LCR circuit equals the resonant frequency, the reactance of the circuit is zero. Does it mean that there is no current through the inductor or the capacitor ?

Dear  NIKHIL GARG, 

At resonance w=1/(L*C)^.5
Altough reactance is zero but impedance Z=R
so current i=E/R
At resonance current will not be zero in fact it will be maximum.
