   Q1. The impedance of a series LCR circuit is minimum when the frequency is

   • A) less than the resonant frequency
   • B) equal to the resonant frequency
   • C) greater than the resonant frequency
   • D) independent of frequency

   Answer: equal to the resonant frequency

   Explanation: At resonance, Z = R, which is minimum.
