AT RESONANT CONDITION

XL=XC @ RESONANT FREQUENCY

RESONANT FREQUENCY MORE IF XL>XC AND LESS IF XL<XC

HERE IT IS MORE AND IT MEANS XL IS HIGH AND HENCE L IS HIGH (XL=360FL)

L ALWAYS TAKES LAGS THE CURRENT

HENCE THE CURRENT LAGS THE APPLIED VOLTAGE

according to the graph of resonance, above resonant frequency, inductive reactance is more than capacitive reactance, so net is inductive and thus the current lags applied voltage
