For the series LCR circuit shown in the figure! what is the resonance frequency and the amplitude of the current at the resonating frequency?

  • -16
Resonant angular frequency wr = 1/ ( LC)1/2
                                                  = 1/ ( 8 x 10-3 x 20 x10-6)
                                                 = 104/4
                                                 = 2500 rad / s
                   At resonance       I = V/R
                                                = 220/44
                                               = 5 A
