Question
Physics Question on Alternating current
A capacitor of suitable capacitance can be used in an circuit in place of the choke coil. 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
Both assertion and reason are true but reason is not the correct explanation of assertion
Explanation
Solution
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
