A LCR circuit is at resonance for a capacitor C,
inductance L and resistance R. Now the value of
resistance is halved keeping all other parameters
same. The current amplitude at resonance will be
now:

(1) Zero

(2) double

(3) same 

(4) halved                                                         JEE-2024

Solution:                
A LCR circuit is at resonance for a capacitor
