Given below are two statements: Statement I: In an LCR series circuit, current is maximum at resonance. Statement II: Current in a purely resistive circuit can never be less than that in a series LCR

Question

Given below are two statements:
Statement I: In an LCR series circuit, current is maximum at resonance.
Statement II: Current in a purely resistive circuit can never be less than that in a series LCR circuit when connected to same voltage source.
In the light of the above statements, choose the correct from the options given below:

Statement-I I m ​ = R 2 + ( X L ​ − X C ​ ) 2 ​ V m ​ ​ at resonance X L ​ = X C ​ Thus, I m ​ = R V m ​ ​ ∵ Impendence is minimum therefore I is maximum at resonance. Statement-II I = ( R V ​ ) in purely resistive circuit.
