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: 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 :
- (A)Statement I is true but Statement II is false
- (B)Statement I is false but Statement II is true
- (C)Both Statement I and Statement II are true✓ Correct
- (D)Both Statement I and Statement II are false
Answer: (C)
Solution
Statement I: In a series LCR circuit is minimum () at resonance (), so is maximum. True.
Statement II: For the same source, a purely resistive circuit has impedance , the smallest possible, so its current can never be less than the current in the series LCR circuit. True.
Both statements are true.
Statement II: For the same source, a purely resistive circuit has impedance , the smallest possible, so its current can never be less than the current in the series LCR circuit. True.
Both statements are true.
