Question

Statement (1): An LCR circuit connected to an AC source has maximum average power at resonance. 

Statement (2): A resistor only circuit with zero phase difference has maximum average power. 

(1) (1) and (2) both are correct 

(2) (1) is correct but (2) is incorrect 

(3) (1) is incorrect but (2) is correct 

(4) Both (1) and (2) are incorrect

Answer 1

(1) (1) and (2) both are correct 

Or circuit is a resistive circuit or an LCR is at resonance.
