Question

For the given figures, choose the correct options:

• A. The rms current in circuit (b) can never be larger than that in (a)
• B. The rms current in figure (a) is always equal to that in figure (b)
• C. The rms current in circuit (b) can be larger than that in (a)
• D. At resonance, current in (b) is less than that in (a)

Answer 1

Answer: (A)

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