Accepted Answer

As the impedance of the circuit $(\mathrm{B})$ is clearly more than that of circuit (A), the current in the circuit (B) will always be less than that in circuit (A). Also, at resonance, $\mathrm{X}_{\mathrm{L}}=\mathrm{X}_{\mathrm{C}}$ and the impedance of circuit $(B), Z_B=Z_A . \Rightarrow I_B=I_A$. Hence, the option (A) is the only correct option.

Answer

The r.m.s. current in circuit (B) can never be greater than that in circuit (A)

Answer

The r.m.s. current in circuit (A) is always equal to that in circuit (B)

Answer

The r.m.s. current in circuit (B) can be greater than in circuit (A)

Answer

At resonance, current in (B) is less than that in circuit (A)
