Answer 2

Explanation:

Sometimes, a crackling sound is heard while taking off a sweater during winters. It is a natural phenomenon. When we take off sweater during winters, it gets automatically charged because of the friction that take place between the sweater and the body. During winter body remains without sweat hence the amount of friction gets higher.  It is static electricity and that is why, one can hear a crackling sound during the taken off process.
