resonance circuit

what is the current charging time in serial
resonance circuit (--R---L----C--)
in the resonance frequency

thx :?:
 

At resonance, the capacitive reactance equals the inductive reactance. Since they are of opposite phase, they cancel. Therefore, at resonance the series impedance of the RLC circuit is just the real part - the resistance. The "charging time" is theoretically zero - the only current flowing is the real component of current through the resistor.
