    Study the circuits (a) and (b) shown in Fig. 4(EP).26 and answer the following questions.                                               (a) Under which conditions would the rms currents in the two circuits be the same?                                          (b) Can the rms current in circuit (b) be larger than that in (a)?

Answer:

                  In Fig. 4(EP).26(a),                                                    In Fig. 4(EP).26(b), Clearly, only when i.e., at resonance only. (b) As Therefore, rms current in circuit (b) cannot be larger than that in circuit (a).
