Assertion : A capacitor of suitable capacitance can be used in an AC circuit in place of the choke coil. Reason : A capacitor blocks DC and allows AC only.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

We can use a capacitor of suitable capacitance as a choke coil, because average power consumed in an ideal capacitor is zero. Therefore, like a choke coil, a condenser can reduce AC\mathrm{AC} without power dissipation.
