Question

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

• A. Both assertion and reason are correct and reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. Assertion is true but reason is false
• D. Assertion is false but reason is true

Answer 1

Answer: (B)

We can use a capacitor of suitable capacitance as a chock coil, because average power consumed per cycle in an ideal capacitor is zero. Therefore, like a choke coil, a condenser can reduce ac without power dissipation
