Q1:

Assertion (A): The impedance of a series resonant circuit is minimum at resonance. Reason (R): Resonance condition implies unity power factor condition.

A Both A and R are true and R is correct explanation of A

B Both A and R are true and R is not the correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

Since power factor is unity, impedance is minimum.
