Question: A coil of resistance R and inductance L has a capacitor C in parallel with it. The source frequency is adjusted to a value equal to resonant frequency. Another capacitor C is added in parallel with the above circuit, the source current will
[A].

increase

[B].

decrease

[C].

remain the same

[D].

may increase or decrease

Answer: Option B

Explanation:

The circuit will not in resonance. In parallel resonant circuit the current is minimum at resonance. Therefore, current will increase.
