| Assertion: The phenomenon of self-induction is helpful in working of a choke coil. |
| Reason: A choked is used for reducing energy loss in the circuit. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and 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.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
The phenomenon of self-induction is helpful in working of a choke coil because higher is the self inductance of choke coil as compared to its resistance, less will be the dissipation of energy per cycle. The power is coil is \[{{P}_{av}}={{E}_{v}}{{I}_{v}}\,\cos \,\frac{\pi }{2}\] is zero because of which energy loss in coil is reduced.
