Capacitor for Spark Reduction

Assertion (A): Capacitor reduces sparks in induction coil.
Reason (R): Capacitor provides alternative path to current when circuit is broken.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

A: True. In an induction coil, breaking the circuit induces a high back EMF, causing sparks across the switch. Capacitors are used to mitigate this.


R: True. A capacitor connected across the switch provides a path for the induced current, absorbing the inductive energy and preventing excessive voltage buildup that leads to sparks.\n(R) correctly explains how (A) works.
