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

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
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

At frequencies above the resonance frequency the series RLC circuit. Behaves as an inductive load (evident from equivalent impedance equation) hence current will lag.

At resonant frequency, (Xl=Xc).
Above resonant frequency, (Xl>Xc).
Below resonant frequency (Xl<Xc).
Above resonant frequency, (Xl>Xc).
Below resonant frequency (Xl<Xc).

At resonance, Xl =XC. Thus there no phase angle. Therefore; no lug or lead.

At resonance I in phase with V.

Above resonance frequency current lags voltage because at this situation XL>XC.

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.

Resonant frequency XL>XC. So current lags the applied voltage.

Resonant frequency(fr) = 1/(2 * 3.14 * (LC)1/2,
Take that root.
Given that RLC circuit is above the fr then we know XL > XC in case fr is more then current must be low and that case current should be lags by applied voltage.
