JEE Main 6 April 2024, Shift 1, Physics Q44

Question 44 of 90 in this shift, Physics question 14 of 30, Section A.

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 :
  1. (1)Both Statement I and Statement II are trueOfficial answer
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is true but Statement II is false
