Q ​An series LCR circuit is resonating with a source whose emf varies with time as 
described in diagram-1. If we replace source by another source whose emf varies with time according to diagram-2, then : 

(1) for getting resonance again,decrease R 
(2) current will remain in phase with source voltage 
(3) for getting resonance again, decrease C 
(4) current will lead source voltage after replacing the source
