Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
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) if the Assertion and Reason are true and Reason is the correct explanation of Assertion
B) if both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C) if Assertion is true but Reason is false
D) if both Assertion and Reason are false
Correct Answer: B
Solution :
We can use a capacitor of suitable capacitance as a choke coil because average power consumed per cycle in an ideal capacitor zero. Therefore, like a choke coil, a condenser can reduce AC without power dissipation.
