Solution

Q.
For the given figure, choose the correct options: [2023]

1 The rms current in circuit (b) can never be larger than that in (a).

2 The rms current in figure (a) is always equal to that in figure (b).

3 The rms current in circuit (b) can be larger than that in (a).

4 At resonance, current in (b) is less than that in (a).

Ans.
(1)

$I_{\max} = \frac{220}{40} = 5.5 A$

$X_{L}$ is not equal to $X_{C}$ . So rms current in (b) can never be larger than (a).
