and a capacitor 
are connected in series to an oscillator of frequency 
. if the resonant frequency is 
, then the current lags behind voltage, when
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The current will lag behind the voltage when reactance of inductance is more than the reactance of condenser.
Thus, 
or 
or 
or 
, where 
resonant frequency
