|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

|At frequencies above the resonance frequency the series RLC circuit. Behaves as an inductive load (evident from equivalent impedance equation) hence current will lag.|
|Manindra said: (May 19, 2014)|
|At resonant frequency, (Xl=Xc).
Above resonant frequency, (Xl>Xc).
Below resonant frequency (Xl<Xc).
|Aggrey Kere said: (Jun 26, 2014)|
|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.
|Sandeep Sana said: (Jun 2, 2015)|
|Resonant frequency XL>XC. So current lags the applied voltage.|
|Pruthviraj said: (Oct 7, 2016)|
|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.

|The reactive voltage VL and VC, does it cancel each other at resonance? Can anyone explain?|
|Nabin Baniya said: (Aug 26, 2018)|
|Above resonance frequency, the circuit is inductive.|
