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:

Options

  1. AStatement I is false but Statement II is true
  2. BStatement I is true but Statement II is false
  3. CBoth Statement I and Statement II are true
  4. DBoth Statement I and Statement II are false

Correct answer

C. Both Statement I and Statement II are true

Step-by-step solution

Statement-I I_m= V_m R^2+ (X_L-X_C )^2 at resonance X_L=X_C Thus, I_m= V_m R Impendence is minimum therefore I is maximum at resonance. Statement-II I = ( V R ) in purely resistive circuit.
