Question

In the following circuit, the values of current flowing in the circuit at f=0 and f=$\infty$ will respectively be

• A. 8A and 0A
• B. 0A and 0A
• C. 8A and 8A
• D. 0A and 8A

Answer 1

Answer: (B)

0A and 0A

In a LCR circuit current at $t=0$ is zero because inductor does not allow flow of current,

and at $t=\infty$ also current is zero because capacitor does not allow flow of current.
